Yeah a vacuum leak was my first suspect but as I said earlier I've checked all the hoses and connections that I can see and get my hands on and all are fine.

Also like I said in an earlier post I cleaned the PCV valve about 2 weeks ago because it was full of sludge and I rechecked today and its perfectly clean. The PCV elbow and hose both look fine as well.

When I turn the key to the "ON" position the CEL doesn't even light up along with half my other warning lights. Not sure what's going on there.

I'll see if I can get it down to autozone sometime this week and get it scanned.

It's had the idle problem since I've gotten it so it's nothing new.

Thanks for all the suggestions and help.
