First post here. I have a 1988 toyota pickup that was sitting for 2 months while in bootcamp got out and drove my truck to san diego where I'm stationed. My check engine light has been coming on after I've been driving for about 20 min but not before that. I was wondering what some of the problems may be. Its my daily driver. Has about 156000 miles has had the clutch replaced once. No problems until now. I also haven't noticed any new sounds or smells coming from the truck. Any bit of help is greatly appreciated
