Question about 1989 Mitsubishi Galant

2 Answers

Gas in oil. Dont know how this is possible, when the car gets warm it will rough idle and will accelerate poorly due to combustion within the engine and black smoke out the exhaust when speed is picked up. I have been told its a cooling sensor or a faulty injector. Based on what i know it takes the engine a while to get warm so im thinking temperature sensor is malfunctioning but i get no check engine light what so ever. Any help would be appreciated. Thank you,

    I changed oil and air filter and cleaned throttlebody. Injector is next on my list. Although it only does it when the car is Warmed up its not continous either.

  • mikey72482 Jan 12, 2009

    smoke comes when really bad. Since oil changed it hasnt really smoked at all in such a bad manner just aggravating ha. And the oil rings are where the cylinders are correct?

  • mikey72482 Jan 12, 2009

    well the smoke has ceased all together.The car set for a while and im thinking in the setting the gaskets or rings wore out or splotched and allowed gas in. It is getting better and better as each day passes. But its hassle of it. I was told by a transmission shop it was probably the injectors forcing more gas through the PGR and causing it to spit in the valves to the oil dut to a malfunctioning cooling temperature sensor. I have pondered and i try to keep my engine as cool as can be so i dont have this issue but i wreckon as much as i am replacing parts and such itll be a new engine. LOL.

I think you have bad rings if oil is getting into the gas. or vice versa...you mighht want to have it checked before driving it a lot further

    it shouldnt be there at all.all it is is a sign telling you the rings are going bad and if youre getting black smoke id say they are pretty well gone or will be soon

  • Ronnie Houston Jan 12, 2009

    yep and it could be getting in through the valves i guess just as easilyit shouldnt be smoking at all and if it continues or gets heavy again id suggest a total overhaul.the rings and valves are the only 2 ways you can get gas in your oil

Hello
this can be from
dirty air filter
leaking injector
dirty throttle body.
do a oil change right away gas will wash your bearings and destroy the motor

Rough idle in drive, correct rpm


Car idle is rough Inspection Service & Cost A rough idling engine can be caused by a number of issues, some of them are serious while others tend to be minor, but the symptoms remain pretty much the same. The car will feel rough and bouncy when the engine is running. The car will also idle below its regular speed, display inconsistent RPMs and may produce a shaking, skipping or slipping sound when the vehicle is running.
While a rough idling engine may seem to be a simple inconvenience it often indicates a deeper problem within the engine. The vehicle should be inspected and repaired as soon as possible because small problems have a way of turning into expensive repairs. How this system works: The idle speed of an engine is basically the rotational speed the engine runs on when it is un-coupled from the drivetrain and the throttle pedal is not being depressed. The idle speed is measured in the revolutions per minute of the crankshaft.
When an engine is running at idle speed it generates enough power to smoothly operate equipment such as the water pump, alternator, and power steering but not enough power to move the vehicle itself. A passenger car will usually idle between 600 RPMs and 1000 RPMs. A properly functioning idle should run smoothly without skipping or slipping. Common reasons for this to happen:
  • Dirty Fuel Injectors: The fuel injection system injects fuel into the cylinders, which creates a mix of air, and fuel to ignite and burn. Fuel injectors have tiny nozzles to spray the fuel into the cylinder and they can become clogged over time. clogged or failing fuel injector creates a lack of fuel in the vehicle's engine. This can cause a rough idle, it can also cause symptoms such as slow acceleration or the car not feeling as if it has enough power. If the problem is addressed early, it is possible to clean the injectors, which will restore them to full function. If this condition is not addressed in a timely manner the injectors will need to be replaced. Incorrect Idle Speed: While the average idle speed falls between 600 to 1,000 RPMs, if your vehicle is experiencing a rough idle it could be due to an incorrect idle speed setting. A trained mechanic can easily adjust the idle speed, and it should stay at the proper speed. If an adjusted idle speed becomes inconsistent or changes at random intervals there may be a bigger problem that needs to be explored. Vacuum Leak: If the vacuum system has a leak, it can seriously affect the ability of the vehicle's computer to regulate the air to fuel ratio. This can lead to a rough idle and if the problem is not addressed the car may experience slow acceleration and a lack of power. Vacuum leaks should be inspected and repaired immediately. Incorrectly Installed or Damaged Plugs: Spark plugs are responsible for creating the spark that allows the vehicle to burn fuel. If spark plugs are improperly installed or malfunctioning, the idle speed can be affected. The vehicle's engine may vibrate or there may be slipping or straining sounds coming from the engine. Defective or Clogged Fuel Pump: A rough idle can be related to fuel delivery issues. The fuel pump, which is responsible for pulling fuel from the gas tank to the fuel injectors, can become clogged or defective. If this happens the engine will not get enough fuel, which can cause a rough idle, sputtering, stalling and even slow acceleration. Clogged Fuel Filter: A clogged fuel filter can cause similar problems. The job of the fuel filter is to screen out contaminants in the fuel, over time it will become clogged and need to be replaced. A rough idle is one symptom of a clogged fuel filter. Failing Electrical Components: A problem or failure in the ignition system or various electronic components can cause a rough idle. If this is the case, the problem will usually get worse as RPMs increase. Common culprits include the ignition control module, plug wires, coils, and spark plugs. Defective Airflow Sensor: A defective airflow sensor can be responsible for a rough idle. A mass airflow sensor detects the amount of air coming into the fuel injection system and sends that information to the vehicle's computer. The computer uses that data to deliver the proper amount of fuel to the air in the vehicle. Over time these sensors can malfunction or become dirty. One of the first symptoms of a malfunctioning airflow sensor is a rough idle. The car may also accelerate slowly and even stutter or stall as the problem progresses. Dirty Oxygen Sensor: Oxygen sensors measure how rich or lean the gases are as they exit the combustion chamber. Depending on the results, the amount of fuel entering the engine is adjusted by the vehicle computer. The ultimate goal is to maintain an ideal mixture that produces the lowest emissions. A dirty or failing oxygen sensor will usually trigger the check engine light and can lead to a rough idle, lower fuel efficiency and failed emission test.

My 94 Toyota Camry 4 cyl is running really rough and stalling out once the engine warms up


1. Error Code 24. Intake Air Temperature Sensor.
Solution:
Check the following:
- IAT Connector and wiring.
- Intake Air Temperature Sensor.
- Engine Coolant Temperature Sensor.
- ECM.
2. Rough Idling when the engine is hot.
The following are the reasons due to which the engine can perform bad when it is hot.
- Fuel pump control circuit.
- Fuel pump pressure.
- Fuel injectors.
- Non Return Valve clogged, located on the lower side of car chassis above the fuel tank.
- Engine compression, valve clearance, spark plugs.

Starts up and dies 3 times in a row. once started, oil pressure gauge not working?


Can you keep the vehicle running if you keep the accelerator pedal depressed?
Do you have an engine check warning light illuminated?
Is there oil in the engine?

Assuming the oil level is fine and you have no check engine light illuminated, then I would suggest checking the following in this order:

1) Throttle body and idle control valve. Clean these thoroughly and rebuild.

2) O2 sensor in the exhaust. A poor reading can result in poor mixture control. You may also suffer poor gas mileage if this is at fault.

3) Exhaust Gas Recirculation valve possibly faulty.

Will intake gasket leak make the lifters tic when first starting


I dont think and intake gasket will cause lifter noise. It may cause a rough idle and or a miss at idle on cold start up . as the engine warms up the miss or rough idle will decrease . As for the lifter noise this could be cause by the lifter bleeding down or poor oil presure . On your model of engine there is no adjustment on the rocker arms for lifter noise . They are a 0 lash type .

Cannot get the back left plug out due to small space. repleaced all plugs and wires except back left and front right. Now the check engine light is on and idles a little rough.


Would it give you any more room if you removed the front wheels and worked through the wheel well? You would need an extra long extension to go on your ratchet. The check engine light is probably caused by the rough idle. If you had trouble getting the plug wires off due to the cramped space, you may not have gotten them back on good, which would cause a miss and a rough idle. I have noticed that many times, when I install a new set of spark plugs, the engine will tend to have a slight miss at idle. This usually happens to engines that have not been tuned up in years. I always attributed it to combustion chamber deposits being burned of by the more complete combustion of the air/fuel mixture from the new plugs. It usually goes away after a couple hundred miles of driving, especially at highway speeds. One thing I like to do to an engine that has high mileage is run a can of Marvel Mystery Oil through the intake at very high idle. You would have to use a small vacuum hose inserted into the can and hook it up to a vacuum source so the engine can pull the oil in through the hose. It it was a carbureted engine, you would just pour it slowly into the carb. If you do this, ve sure the vehicle is outside with plenty of ventilation. Once the Marvel Oil starts burning in the combustion chambers, there will be lots of white smoke pouring from the exhaust pipe. This is normal, and it will clear up once the oil is no longer being fed to the engine. The Marvel Oil will clean all the deposits off the combustion chambers and also the top of the pistons.

Hi I have a 1991 Olds Cutlass Supreme, with a 3.1 liter engine. My problem is when the car warms at stops it runs rough. Sometimes shuts off. Sometimes when crusing at speeds 30-50 the car sort of jerks...


My 3.4 liter 91 Cutlass Supreme has similar problem when warm the engine misses (car jerks). But its fine at idle and without any accelerator pressure. The SERVICE ENGINE light also comes on intermittantly. I am going to test the ignition coils.

Golf GT Tdi 115 - performance when warm.


you dont say what miles the car has done.but you should now be using semi synthetic 20/50 oil and try using a fuel additive(redex/wynns)to clean the injectors.if you are using oil it is possible that the engine has lost some of its compression due to ring/valve wear.did you know that to convert your engine to a 130/150bhp unit,you only need to change the ecu try"diesel tuning"website.....

When I start my car there is gas smell and it has poor acceleration. The acceleration gets better as the car warms up... The car also idles rough.I recently had an oil change I also changed the spark plugs...


the gas smell makes me think EGRS (Exhaust Gas Recirculation System) check all your Vacuum hoses, start at your charcoal canister and work backwards.

A vacuum problem explains your conditions at least...

Rough idle and acceleration


I am not a mechanic, so I dont know for sure, but it sounds like a problem I had with my car. It turned out there was a bad wire. We serviced the wires and spark plugs and problem solved.
