Alright quick question, i know that P0137 is an Oxygen Sensor, and i know that P0327 is a knock sensor. Now i dont know exactly what i need to buy. Do i have to buy one knock sensor and one o2 sensor since theres only two codes? Or do i have to replace them both, and i don't know which one is bad or how to tell.
 


Exhaust sputtering sounds

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.
 
Re: Exhaust sputtering sounds

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.
 
Re: Exhaust sputtering sounds

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.
 


Wow, around $30 on rock auto. This seem correct?

If you have straight pipes then it will make weird noises when you back off the gas because there is nothing to muffle the ****ty sound of a 3800.
