First find out what the code(s) are by having them read. If you don't have your own code reader then try Autozone which can read them for you for free.

Once you have the code(s) then you can begin effectively troubleshooting the car.

I was going to say the same thing. GMTA heehee.


scottIN, if you plan on doing any more mods or tweaking the mods you have made, an OBD/CAN tool will probably be a good investment.

Okay, go the codes read:

P0159 (3 times)
P0139 (3 times)

She said it was showing it as the O2 sensor.

P0159

Not sure what mods you have but I'd checking for intake leaks. It's hard to believe that both O2 sensors failed at the same time. It's also hard to believe that an exhaust leak appeared on both banks at the same time.

I figured those were both banks. And I thought the same thing - weird to have problems in both at the same time since they're essentially independent.

I didn't have them clear the codes, but I just ordered a code reader and will first check for leaks, clean at least the front senors, erase the codes and see what happens. At least now I'll have my own reader - I thought they were like $300 but I found a highly rates one on Amazon for $42.
