What he's talking about a lot of service dealerships refer to as an induction service. They blow this solution through the system under high pressure and it does work, at most dealerships it shoud run anywhere from $60-100. One thing that I would do as well would be to change the spark plugs, and spark plug wires. Also fuel filters on most vehicles are easily accesible and not that hard to change. My highest recommendation for plugs is NGK and NAPA autoparts has spark plug wires Belden MAXX that work wonders. I used plug wires from O'Reilly's before and even though a wide variety of their products are great my car performed worse after putting those on than it did before.

That's probably because you've got a lot of carbon build up in your engine's combustion chamber.

The best way would be to restore the power and speed would be to have a carbon ridding solution injected into the engine. The solution will liquify the carbon and other build-ups, which would then restore the "power" of your car. You'll get better acceleration, higher rpm and top speed, etc. have a mechanic do it for you. It's alot cheaper and faster than having the engined overhauled.

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.

Car speed slows down and speeds up runs a little rough when speeding back up it does a jerk.


Dear Debbie,
Fuel filter costs about $ 20 plus installation, catalytic converter about $100 up to $ 600 plus installation..
Go for the fuel filter first.
If it is not that, do a diagnostic check before you do the catalytic converter.
The "cat" seldom is the problem.
God bless your efforts.

yes there is a trottle position sensor.
but first have engine code retrieve if any
if it run rough idle we don't talk tps
spark plugs, wires,fuel pressure if it's good alot of to do
if you have a scanner you could see the data

Rough idle


Sounds like a automatic choke sticking....Take the air duct loose from carb..While accelerating engine spray bottle throttle spray in.....as the car tries to die...stop spraying...Repeat 3 or 4 times.....It will clean your injectors. Runs alot better...Remember....bottle throttle spray...not carborator spray

1995 nissan pickup bogs down,feels sluggish


if the car starts then there shouldn't be anything wrong with your fuel pump. fuel pumps either work or they don't. it sounds like you may be having a problem with your mass air flow sensor you can try cleaning it with an approved aerosol spray or it may need to be replaced. hope this helps.
