Question about 1998 Mercury Grand Marquis

1 Answer

My check engine light came on and my car started sputtering. it sputters at idle and low rpms. at higher rpms it sounds/feels normal. if i keep the car at a constant speed the engine does it more, and twice the check engine light flickered while i was doing just that. whats up? could it be the IAC?

It could be the idle sensor. If your check engine light is on, get the codes. It it is the IAC, it will pick it up.

Go to the auto parts and get a container of Heat fuel treatment and get a new fuel filter also. Then pour in the proper amount of fuel treatment and change the fuel filter. This should fix your problem. Also when was the last time you changed the air filter. This would help it run better and increase your mileage.

1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle


ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week

2001 Dodge Ram 1500 engine sputters at low rpm


hello i am a independent shop owner and i recently had a 01' dodge 1500 5.2L engine and it seemed to have the same symptoms as your car, i checked fuel pressure and it seemed to be around 49 which is still considered normal and also i did check the distributor cap and each spark point had corroded parts on the tips but before i replaced any parts i disconnected the bank 1 sensor 1 oxygen sensor and noticed that the car never sputtered again.. so in my case i recommended to my customer to first replace the o2 sensor! Hope this helps cheers!
