Wow! Thanks for all the inputs.
Rtjny99, yeah 35 isn’t all that cold, but it’s a range where the problem seems to crop up. In fact I’m in MA and I get grief for complaining about the lack of snow this winter.
cigroller, I need to get back to my friend with the code reader but I’m sure one of the codes was one of the ones in thelink I posted. That code was P0638 "Throttle Actuator Control Range / Performance (Bank 1). I can repost tomorrow hopefully.
Raj, I’ll check your link as well. Thanks again.
