I just checked codes from my ECU and here is what I have. 0304 and 0303. I am so ****ed off right now. So that means I have a bad knock sensor? What do I need to do to fix code 34? It also says that code 33 is a Front Left Heated O2 sensor. What could be the problem here and what do I need to do to fix this? If this serves any importance at all, I have a 97 GXE and I have a y-pipe and an intake. Thank you.

I recently read that if you get the KS code with an O2 sensor code that if I replaced the O2 sensor then maybe the KS code will go away. Is this true? Please help.

its probably the o2 sensor code thats setting off the knock sensor code

Would you say this is hindering a little bit of performance in the low end? Does anyone know where I can get a new O2 sensor, and what exactly does the O2 sensor do? Thank you for your reply.

I am officially confused. After I got the codes from the ECU earlier today, I reset my ECU's codes. I took it for a 20-30 minute drive and then checked the codes again from my ECU later on in the day and it gave me code 0505 (No Problems with Engine). I don't understand it, why did it say I had a bad O2 sensor and Knock Sensor earlier? By the way this is the first day I have ever checked my ECU for codes.

wait a few hours or days of running the car, it should come back
