Having problems with your 1999 Oldsmobile Intrigue ?
I have a 1999 oldsmobile intrigue that is misting a lot. It idels rough, and runs rough. I can still take off it is a little slow, but I can still go pretty fast, but it still mist at the high speeds pretty badly. I have checked the mass air flow sensor, the oxygen sensor, I have replaced all spark plug and spark plug wires, and still nothing. The computer at Autozone said there were three codes on it, Misfire in 4, Oxygen Flow Sensor, and Mass Air Flow Sensor. After we changed spark plug a
Fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck
