So I installed the active headers and now I'm throwing codes for misfires. I didn't tighten all the headers completely. It was really hard to get them to where I did but we couldn't hear leaks. I also don't know if I hooked up the O2 sensors properly. Could those two things be the reason for misfire codes? Please help. This is my daily driver. I'm taking it into a shop today to get everything tightened. Hopefully that fixes it.
Codes are p29d0, p29d1, p29d2, p29cc, p29cd, p29cf, p29ce, p29c24.

I got misfiring but didn't check codes. Turns out my connections to the coils weren't pushed completely in. Everything ran great after words. Check those too!

So I just checked the forward O2 sensors and they are indeed on backwards. Gonna have to wait until Thursday to swap them though.

Basically it looks at the readings and adjusts the fuel as necessary. So if you have hen flipped flopped basically one bank will run rich, the other one will run lean and they will diverge |
