Ok, my tC is acting up. I think it's my O2. the engine light keeps coming on and the car goes into safe mode. It acts like its missing and back fires. I have the anti-fowler, because I have a full exhaust with header. Anyone been through this? I have a turbo I am putting on, but I need to wait to make sure the car is ok. Thanks.

 

Yeah an o2 can do that. It can cause the engine to run lean which can cause misfires and possible stalling out when you are stopped or at a low rpm. Just a suggestion though...

 

thanks, which O2 do you think it is?

 

ok, the code said it was the 2nd O2, so I got an O2 sim and it works better but still throws a cel, if I put a cat on my mid pipe and put the O2 a few inches behind it, will that work ???
