My car keeps throwing these. I did a search and not sure why it is throwing it. My headers have been on for 2yrs now. All the wires look good. I have a scanmaster and I can clear it but after some driving it comes back again. The L-trims and O2's look good. I just had my tranny worked on and watched the guy use some kind of lube to put the y-pipe back on with. Do you think that might have killed the O2's? But the pipe is after the O2's. And the o2's are a few months old. Thanks...

 

I have the same problem. I replaced my o2's and it didn't help. I know it's probably not right, but I just deleted these codes for the time being because I can't find anyone with any information to help me.

 

Thanks...I might try replacing them but they are new and I hate to get some and they not be the problem.

 

I got the same codes dude. I was told that it is the front O2 sensors, I just did some price checking at advanced and auto zone. They are like 70 bucks a piece. Iwould hate to buy these an my problem not go away.

 

Thats what I did and it didn't fix it.
