hey guys,
i have a 2003 GMC envoy with 242K miles on it. i have never had a engine problem with this thing till now. The oil pressure gauge started reading erratically and going to 0 and check gauges would come on. i replaced oil pressure switch which solved that one. the problem i have now is that when starting the envoy when warm, it either instantly starts which is uncharacteristic or it will crank longer and normal and when it catches, it sounds as if it is not going to run, but does end up running, then sometimes when we shut it off, it will diesel for a second at the most before shutting off. any ideas?
