Well I can't seem to find anything on ebay for a good price. I want something in perfect condition or new although I know that's a longshot. SDPC sells these for $43 each, and I don't want to pay that much. Thanks.

 

DO NOT BUY THEM OFF EBAY! I bought O2 sensors off ebay from a seller with 2000+ positive feedback. The first time, he sent me the wrong sensors and claimed they were the right ones, then accused me of not having a 2003 year tahoe and that's why they didn't fit. So finally (after a month) sent those back to be exchanged, and got the ones with the right connector, and the check engine light came back on a few days later... bad O2's. I just bit the bullet and went to the dealership and paid full price, but at least they worked!

I got my knock sensors from GMPD for $90 for 2 shipped.

 

do you know if the ones off of a 01 5.3 would work. I have 1 used that you can have. I changed both because the rear was corroded. the front was fine though. I figured while i had the intake off I would change them both.

 

no thanks dont want something that old.

 

Just buy new ones and be done with it.

 

give me the extra money and Ill do it

 

I have a set for an 02 5.3, you find out if they work and make me a reasonable offer.

 

are they from 2002 or are they replacements?

 

Genuine GM parts for an 02 5.3 that I never installed. Had a code, bought them, code went away, and just held onto them.

 

I'll give you 50 shipped.
