When's the last time you've changed plugs? Are they stock cats(how many miles)? That that chicken up to AutoZone and find out what the code it. There is a glossary of codes located in the newbie tech

don't know when the last time the plugs were changed i have had the car for six months only driven it for one due to all the title bullshit. it has 118,000 miles on the stock cats I'm going to to do long tubes and 3 inch cutouts with a true dual exhaust over the summer. i got the code it is bank one reading lean so I'm going to pull the O2 tomorrow and switch it with the other one and see if changes if not well i will see if i have fuel delivery issues.
Thanks,William

Sounds like the same issue I'm having on mine. Changed 02 all rd and still throwing code. You're on the right track w changing exhaust out, pull all your egr too if u can spare the time. Then find someone to wipe all that from the comp and you'll b golden.

I'm having the same issue on my 99 trans am. Its all stock but just had the motor overhauled due to a warped head and coolant in the oil. Anyways now mines saying bank 1 lean sensors 1&2 low voltage... I plan on doing longtubes / ory / ota catback when I get the money in a few months so I'd just like it to get me by for a few months. Anything you find out will be helpful so post it up! Thanks

New O2 sensors did nothing so now I'm going to check the fuel pressure and see if a injector is bad or clogged up.
