  1. So I cleaned the throttle body (very dirty) and checked out the MAF and air filter yesterday, everything checked out. Didn't fix the problem unfortunately though still happens, mostly at night and mostly when the headlights and blower motor are running. So I'm thinking alternator?

  4. Thanks for all the input, I’ll see if I can get my hands on a good scan tool. thanks, Gabe
