Bad 02's will mess up just about everything on the car. Order them online from amazon or rock auto they are about $32 for the good Denso brand

Pull the code. See if you lost a coil. Probably feels like it's down on power, huh?

You can buy the C5 rear O2's for the longer pigtail vs. extensions. Any other reasoning is speculation.

Surely get them scanned, I bet it will be o2's. Driving on bad front o2's can really jack your car up. Been there, done that. If you already have LT's you already have extensions unless someone did a hack job on your existing ones which could be why they went bad in the first place. If you don't have extensions buy the longer ones, they are the same.

Does it backfire in between shifts at high rpms during WOT runs, or during normal driving?

No they don't have to be off a Z06 all 4 of the sensors on the camaros and corvettes are all the same except the length of the wiring. The vette sensors have longer wires so you don't have to buy extensions or lengthen your current one's. If the 02's are really old it's good to replace them on any car because they get slow over time. But nobody here knows your problem and nobody can say with certainty the 02's will fix it so...

Get the codes then go from there.

Report back with codes before you go slapping parts on that the doofus at Autozone says you need.



I have a question, does your temperature gauge work? What temperature does it run at once it is warm?

Okay, if the coolant temp sensor is bad it will run rich, sounds like it works.
