too old of an olds
Hey guys, I got this 1990 oldsmobile cutless in my bay. The issue is the car has terrible emissions when going through inspection, the car drives great and the 3.3 v6 runs smooth. Its got about 98k on the clock. I want to test the obd and see what codes flash. I think it could be a bad o2 sensor or the cat is filthy and needs to be replaced. Anyone know where i can get a pin chart for the obd connector or where i can find a chart of codes to look at while i test the obd? And if you guys could throw up any info on the cars problem, im all ears.
