 Subject: Check engine after Exaust install...
IP: Logged
Message:
Hey all,
I recently installed a 3" high flow cat and 3" cat back to a dual 2.5" outlet muffler and pipes. I also installed new O2 sensors while I was in there.
The engine starts and runs OK, a little rough at times but I figured that was because of NO back pressure. :-D.
On occation I will get a check engine light when I start it and it will stay on for a while. It may stay on all day through multiple starts or only happen once and not do it on the second start.
This may have to do with the mixture possibly because of the new exaust and the o2 sensors reading different. But I am not an expert by any means on this OBD2 stuff.
Any help or advice would be appreciated since this is my daily driver now and I want to fix it before anything serious happens.
Thanks
