Hi Guy's I have installed long tube headers on my 97 vette, getting a Po153 code, slow response! In on the installation of the headers, I had to install extension to the back o2 , Bank1 , after driving the car and checking back under the car, I found one of the extenction wires to one of the o2's were touching the header,and the coating was burned off! I found the wire was a little short so I cut and added a couple of inch's to it! I took care fixing the wire with sodier and shrink tube , Started to get these code! I have not done any tune to the car yet! car seems to run very strong! Could these code's be from the high flow cats or may be from the wire I repaired! I know with this code the pcm will lean out the car! What can i do to stop this code from coming bank! :welcome:
