Clogged fuel filter or bad fuel pump. Check fuel pressure before and after filter. Could also be a mass air flow sensor going bad or a air leak in the intake manifold.

SOURCE: V6 engine idles rough after restarting, then smooths out

My first guess would be a dirty carb/fuel injector set. Run some fuel cleaner through the tank and see if it gets better. You might have to do it through a couple of tanksful. How long since you've had a tune-up? It might just be that time.

SOURCE: 1999 Toyota Camry V6 idles rough and stalls after

yes it could be a fuel related problem, when was your last tune up, it could also be a spark issue, old or corroted spark plugs will sometimes not put out the correct amount of heat to ignite the gas correctly till it runs for a while, if the check engine light isnt lit, it will almost have to be something simular to this

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.

What would cause the idle to jump up and down upon starting the vehicle?


Sounds like you've done everything but the injectors. Run a bottle of fuel injector cleaner in a tank full of gas every time you do an oil change after this time. Also, check the fuel pressure to see if it's where should be for the injectors. But then, if it has enough pressure to go through the dirty injectors to make it run, pressure should be good. Check it anyway.

clean the idler on the intake and also clean the throttle sensor, it would also be best to change the air filter and clean the maf sensor. Idler does more than just idle vehicle it controls low revs, and drop down from reves. throttle sensor tell ecu what air to add to the fuel. and the MAF tells ecu how much air is coming into the intake. also check for broken cracked vacuum lines.

5.3 liter Chevy engine #1 Cylinder not firing at idle


My opinion...

Year? Miles?

There's no way I'd dive into a "HEAD GASKET"
diagnosis without pressure testing the cooling
system and (wet/dry) COMPRESSION testing
the whole engine...

Even if it is a "HEAD GASKET"... the entire engine
might be ready for a REFRESH... and tossing a new
Head gasket into a TIRED ENGINE not insubstantial
(a lot of wasted time & money)...

Come back with some compression numbers...

but don't bother with any of this if your engine oil has water in it.

We just purchased a 2002 Ford Escort. Tonight, when starting the car, it ran very rough and then died. We started it again and it ran fine after that. It has happened twice and it has only happened when...


Could be a idle air problem. The injector could be leaking when you shut it off ..Try some injector cleaner see if it gets better..The idle air shouldnt run rough just idle real low or sometimes it will get stuck and idle high....Are you losing any antifreeze..If you are the 2.0 SOHC engine bad about leaking antifreeze into the cylinder and makes the engine run rough until it burns it out..See if you can see the smoke coming out when it happens..White smoke indicates antifreeze,,Black smoke indicates fuel..

I bought a second car for utility use; B6000, 1994, p/u, standard trans. Only when starting and running when the engine is cold, it runs very rough and difficult to idle. At normal operating temperatures...


a coolant tempurature sensor will make it run to rich if it is bad. run rough at idle, and produce black smoke, engine may stall out. it also causes retarded timing, slow idle speed, cold hesitation or stumble, poor fuel milage. good-luck!! if light is on check for problem code. this will guide you in the right direction. if no scanner, any auto parts store will scan for free. repost if need be. have a good day!!

Sounds like one of your chambers isn't firing. Run your car for a few minutes, shut it off then pull your plugs one at a time and see if one of them is wet. Might just need a new plug.
