Could be in need of a tune up with spark plugs, spark plug wires, air and fuel filters.
Why does my 2000 Pontiac Grand Am, with a 2.4L engine, run rough at idle but runs normally when placed in neutral? I changed the plugs and air filter, but the problem continues.
Stalling rough. Like stalling while on a hill. That made mine skip.
How many connections should a alternator have on a 96 Pontiac grand prix
The car will start but it will run rough and will probably overheat and cause worse problems.
check your mass air flow sensor. Im having the same problem right now with my 1991 Pontiac Grand Prix & i had a mechanic tell me it was my mass air flow sensor.
plugged catalytic converter
you need a new ignition control module
Poor fuel miliage, rough idle, no start, poor acceleration, stalling.
Rough idle, low injector pressure Sputtering stalling. lack of power
A rough idle and stalling in a 1994 Buick Roadmaster can be caused by several issues, such as a dirty or failing idle air control valve, a malfunctioning mass airflow sensor, or vacuum leaks in the intake system. Additionally, check the fuel system for clogged fuel filters or failing injectors. Ignition system problems, such as worn spark plugs or faulty ignition coils, can also contribute to these symptoms. Conducting a thorough diagnostic can help pinpoint the exact cause.
yes mine had a really rough idle and it turns out the motor mount needed replacing
It can cause a rough idle and random misfires because the engine will be off balance. If the flywheels happens to stop with the missing teeth (tooth) in the starting position, the the engine will not even crank.
