Thread: P0137, P0327 codes question

Its only when i get the car moving a bit faster, maybe after a faster acceleration. Its only when i get off of the gas, theres a sound coming out the back like if you would make a "fart sound" with your tongue. I also have SES codes P0137 and P0327 if that has anything at all to do with it.

Bump

what are those codes? I'm to lazy to look them up. Sounds like your backfiring though.

O2 sensor and knock sensor. Also, those are your tail lights in my sig pic.

Tails look good, what exhaust are you running?

The guy i baught it from said its straight piped into two thin bullet mufflers on each side. Its a rather ****ty sound. I ordered the stock mufflers yesterday. I read that it backfires sometimes when an o2 sensor is bad, which is my case.

Merged the two threads about the two codes,
