After installing the 3" exhaust on my '97 aero, I get a check engine light after an hour of driving. The exhaust has been tried and proven on other 9000's so I'm sure it's not the cat or the exhaust setup itself. I replaced the front O2 sensor a 30k miles ago. Here's the thing. When the exhaust shop built my system, they mounted the 2nd O2 sensor before the cat. I have had that fixed but still get the CEL. Can I pull the codes on this car to make sure it's the exhaust? I can check the O2 sensor's output but any other suggestions?
