First off...Thanks for your help...this site is awsome.... Here is the deal, I went to the "Zone" and got the exact codes that my CEL was giving. It gave a Knock Sensor Malfunction Bank 1 and then it gave me the

"P0136" Code for the Rear O2 Sensor. Should I change the rear 02 sensor first, since that is the code that was showing, or should I change the front O2 Sensor?

 

I thought I read somewhere that one reason for the computer giving the rear O2 sensor malfunction was because it was actually the front sensor causing the problem.....Is that a possibility?

 

Any input would be great.

 

Thanks
