CEL- No Overdrive
A month or so ago the CEL came on in my '93 4.0 auto ranger. I was cruisin at about 60 and it jumped down a gear(pretty hard) and never would go back into OD. Then i find that it doesnt idle very good and even dies sometimes. I've covered the small things like, IAC and MAF. Every now and then the light goes off, OD comes back and all is well for a few minutes. And if it has anything to do with it at all, my valve cover started leakin at about the same time..im stumped. Anybody have any ideas...this thing is drivin me crazy.
