Well a while ago after running my car hard, the o2 sensor went causing it to run horribly, so after replacing that it still ran like ass, misfiring at start up, hesitation with throttle, and its been sucking down the gas a bit faster. I have replaced the plugs/wire, fuel filter, checked various sensors, checked out the condition of my vacuum lines. Right now i am clueless on what it could be, friends think it could be internally from accidental over-rev one night.

What do you guys think? I've searched the forums already but came up with nothing!

THanks in advance

How do you over rev something with a rev limiter?


And what CEL code are you throwing?

And which o2 sensor did you replace?

Missing 4th gear and banging off the rev limiter hardcore. I either went into 2nd on accident or just missed 4th gear bad. I replaced the up stream o2 and didn't get a code untill a week after. I got it checked and it was an a/c sensor, which my a/c isn't hooked up anymore and said Bank 1 is reading rich.
