check for ghost codes, the light does not need to be on to have codes stored. I would also check your vacuum lines as these can have strange impacts on a idle. check you pcv valve to make sure it is working proper

My 91 oldsmobile 98 runs rough in idle but when driving run smooth.


Rough idle is a very common problem on 4 cylinders, but I believe the 98 Regency has a 6 cylinder in it, right?

Sometimes the coil packs get iffy, and sometimes the EGR Valve gets a leak in it causing a rough idle.

When the accelerator pedal is depressed, it can change things so that the engine seems to run smoothly.

However, I would look for codes to see if anything intermittent is occurring in the engine that may need attention.

The OBD-I scanner can help to diagnose the problem, if anything is out of specifications on the engine in question.

The owner will have to find a technician that has such a scanner.

Check engine light comes on temporarily - engine chuggs at idle


Before changing you pcm try cleaning your egr valve. remove the valve and see if its stuck in the open position if so use a small pick to clean around the spring.
