Hey guys I left work today drove about a mile and stopped at a red light and while waiting my truck started revving up and down on its own. As the light turned green I prepared to be moving to the shoulder but the truck ran fin and did t do it again. Is this a precursor to something or what should I check to see what the problem might be?
It's the 3.slo I've checked vacuum but like I said it did it once and that's it. Was thinking maybe the idle censor or something. I know the truck is super cold blooded and spudders if I try to drive and she's cold. Just seemed really weird. Going to do some work on her this weekend, coolant flush oil. Harangue and try to find out what's rubbing or hitting in the front... Any other ideas? And malessohomevrown, was thinking maybe the MAF sencor got some water on it, maybe I'll spray it with some MAF cleaner this weekend. I do have a home made cold air on it...
