These motors have MAP senors instead of MAF's... maybe coolant temp sensor, MAP sensor, or fuel pressure regulator.

If the vehicle is low mileage and no physical ingition problems or MIL lamp on w/ a computer issue, try removing the mass air flow sensor and cleaning it with MAF sensor cleaner (CRC makes it). Dont use throttle cleaner, it must me a alcohol base cleaner (not petroleum). Also clean the throttle plate and idle air passages. There are the first steps before you start throwing allot of parts and money at it.

Stalling at low idle


I don't know this specific car. But, if it has one, check your Idle Air Valve. This can cause the engine to stall. If you can hold the gas pedal and the engine will continue to run until you let off the gas, it is likely the IAV. It will not necessarily cause the engine to run rough. That could be a number of things like spark plugs, wires or dirty injectors. It could also be a compression problem. Is the check engine light on?

2003 ford f 150 4.6 v8 and the idle went from smooth to rough also sputters and sluggish while driving check engine light is flashing.


have the vehicle scanned for error codes at autozone, its free. Post codes for more help....These engines have issues with the COPs (ignition coils-over-plugs) failing prior to 80k miles. When they fail typical problems are: Sputtering under load/acceleration, rough idle, random misfires, random stalling, light or heavy jerking under load (usually at 15-35mph and 45-65mph)..hopefully this helps!!

95 cadillac eldorado engine stalls rough idle check engine light is on


I have a 1994 Cadillac Eldorado and every time i start it the car has rough Idle and the Idle fluctuate's. I also can feel it in the gas pedal when the car is doing this I tried replacing the throttle body sensor but it still does it I also was told it was the Idle error sensor. So instead of spending the unecessary money again I thought I would go online and see if anyone could help me with this problem.

Rough idle


I took mine in to change the plugs and they said there are four O2 sensors in the fuel mixture system and two were bad. I didn't replace them since they were a little pricey ($500 to replace both) and I have 103,000 on the car. Has very similar roughness and occasional oscillations, but no stalling. Hope this helps.
