    can I flash PCM to remove CARB emission programming?

    Hi All, replaced one side downstream sensor with a Bosch 15898 and then the CEL code shifted to only the other bank...so I replaced that one with the a Bosch too and I now have no CEL...I guess this confirms previous posts that CARB cats are not different but rather just go through a...

    can I flash PCM to remove CARB emission programming?

    Question for you guys…downstream sensors only check emission function of CATs right? If I space them out of the exhaust, it won’t change my fuel ratios or anything right?

    can I flash PCM to remove CARB emission programming?

    Cat is Davico it was $500 Oxygen sensors were all from 1A auto Did manifolds and gaskets too because I had a tick…they are not leaking for sure. Cats were done a year ago, I’ve tried spacing the downstream sensors, clearing codes, putting some marvel in the fuel tank etc.

    can I flash PCM to remove CARB emission programming?

    Hmmmm that would be great…how does this tune happen? No I’m not sure I fixed what took the first cat out…to be honest I noticed when I removed the old Y pipe that only one of the 2 cats had the CAT mesh in it so maybe it only went bad because the material was knocked loose? Anyway, it’s all...

I am still getting the code, so after some research I have found my tahoe is built to California CARB emission standards...so...

Since this...

    New autoride compressor & rear shocks, no compressor turn on?

    Ok, I’m still hoping that’s the case with mine but I’ll also check for power in the harness at the relay as suggested

    New autoride compressor & rear shocks, no compressor turn on?

    No, I had the wife turn key on and I held relay, nothing. I tested the relay on 12v on bench and it clicks over fine.

    New autoride compressor & rear shocks, no compressor turn on?

    Hi all, Bought a 2007 tahoe with autoride and the compressor never turned on and rear shocks were bad. So, this week I replaced rear shocks and compressor with all new components. The shocks improved the ride immediately but the compressor is not turning on, ever. I checked all 3 fuses and...
