Anyone out there in 4X4 land have an Idea on this? Benn having this problem on my "86" S-10 Tahoe. It has a 2.8 and keeps comming up with code32 Is there some way to figure this thing out? Someone online said to permanently close the EGR but doesn`t the EGR regulate the timing? And if this can be done,How do you do it? any input on this is better than none.I don`t want to give up and send her to a mechanic as of yet.
