CEL on and off randomly

[morpho18]

My check engine light was going on and off all weekend, so I decided to pull my engine codes to see if that would diagnose any problems. I got 111 codes on KOEO and KOER, with a code 332 stored to memory on both tests. Does this stored code hold any answers for my problem?

Also, every now and again when I start the car, it will drop RPM's until it dies, and does it for a couple of times, then is fine.

Any help would be appreciated.

Sounds like you may need to root out your EGR passages in the intake. I'm on my way out the door, but if you search the forum for "332" or "nostrils", you should find loads of info on doing this!

Yes, for the CEL. Click SEARCH, then enter 332, my user #, and this specific forum. You will find my diagnostic procedure.

For the stumbling idle, it is mostlikely a sticky or failing IAC valve. If cleaning it doesn't help, replace it.
