Pulled these off hp tuners


I see a lot of old information on this but will my car run ok throwing these codes and has anyone used the vette 02s yet?

anyone have a vett with 02s for sale?

 

You should just get Bosch O2s, if anything. It is probably your headers. I doubt that O2s fail in pairs that often. Especially on a 02 vehicle. Unless of course you tuned your vehicle completely out of it's range to adjust your fuel mixture.

 

I have the P1153,P1133 codes too,but I dont have any headers just a y pipe.
