2002 Sunfire Shaking at idle, rpm needle jumps 500-700, CEL

Recommended Posts

Hey y'all!

I picked up a 2002 Sunfire to use as a beater over the winter and I would really appreciate the experts opinions on this before I start working on it. I'm going to code scan it later, but for right now here are the symptoms:

Check Engine Light is on.

Shaking at idle - rpm needle bounces between 500-700 during these episodes.

No abnormal smells so far as I can tell.

Otherwise drives just fine in both city and highway conditions, and fuel economy seems okay.

Any of you seasoned vets have helpful tips?
