For the past 2 weeks my '97 deville (northstar 32 valve v8 engine) has died while idleing at stop lights or stop signs ect. At the same time the oil light will come on. I can throw it into park and start it back up right away. I've checked the PCV and its moving freely but I cleaned it anyway. I didn't hear any hissing so I don't think its a vacume line. Anyone have a clue as to what's going on? It's driving me batty :banghead:!
