FYI: sorry about posting so late about this, but the problem turned out to be a leak in the pcv valve hose. replaced the hose and valve and all was well... Guess its just the simple things sometimes. Too bad I never checked this before I spent over $200 at the dealership

Default pcv

These cars sometimes blow the hose off the PCV which is why I put clamps on my Vin C motors that I maintain.

Yeah, that PCV valve can be quite tempermental. Mine blew off too. Bit of silicone fixed it..

Never thought of a clamp.. how would that work? pics?

I had this exact symptom with a 90 SSE. Would not idle, but it would start and run fine. Anytime you would let it idle, it would just die.

Drove me nuts. Finally traced it down to a bad connection on the battery terminal. Cleaned up the battery terminals and problem disappeared. When it showed up again a year later, cleaned the battery terminals again, and it disappeared again.

I also had some wierd ECM related problems on a GM diesel that were resolved by cleaning the battery ground connections. Now I always clean battery and ground connections first.

Default Thanks!

This started for me last week. Cleaning the terminals worked for me. This forum has saved my butt again.
