Your CEL should illuminate every time you turn your key during an engine start up. I think it comes on when the key gets to the Accessory position.No check engine light But it could be burned out.
Thanks for the input. Still snowin here so cant get to it yet. I'm also thinkin its another problem. My alternator. As last night drivin home my lights would get brighter with acceleration & dim when off the throttle. This causing the battery not to run @ 12volts which inturn the car wont idle properly. Any thoughts??I'm thinking it is more likely the PCV valve. It's only 5 or 6 bucks at the dealer and less than five minutes to swap out. If this has never been replaced, it is almost certainly the problem.
Cleaning the MAF and TB may also help, but the PCV is easier and more likely related to the problem you are describing.
Well finally got under the hood. Cleaned my Throttle body & MAF. Idle went way up but has seemed to come down to the line below 1000rpm on the tac. So well see if this cured my problem as it was very intermitent. How do I pull the pcv valve out I was having trouble checking it as it didnt just pop out as I assumed. Thanks again for all the inputI recently bought Mass Air Flow sensor cleaner and Throttle Body cleaner from a parts store and they worked great. Both the MAF and TB were very easy to get to and clean. Cleaned the TB right on the truck. Fixed my low idle and post start stall problem. Both were very dirty at 60K miles. Can recommended cleaning them both every air filter change. That's easy enough. According to my repair manual my PCV valve was working but they run $10 or less and stupid easy to change so did that too.
