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!

Well since I couldn't loosen the header bolts with the connections in, I disconnected them. When I reattached them, they weren't completely in, The M Shop (who did my tune), was going to change my coil but decided to check first. And voila! No more misfire.

I never touched mine though. I contacted AA with the codes and he said that one of the codes I was throwing was a swapped bank 1 sensor 1 O2. Would that cause the rest of the codes?

If the O2 reading are wrong, it wil cause the car to misfire. Fix that problem first, then we can work on the rest of the issues.

Oh I see, I'm unsure. Sorry, maybe Axiom can chime in. I made sure I tagged all my O2 sensors before the install

Yeah I'm a dumbass. Should've taken it to a shop but didn't wanna drop another 850 bucks on it. I'm scheduled for Thursday @ 9 to get everything tightened. I'll let the guy know to swap the O2 sensors.

O2 sensors for sure. I had the same problem.

Ask your mechanic to read the fuel trims, That will tell you everything.

No, you would be a dumbass if you did take it to them and paid $800 for install. Simple mistake.

If you swap the O2 by accident the car will run like crap. It's easy to mix up if you don't document.

Yes it does.

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

How could I tell if they are in the right spot?

Car won't idle like crap basically.

I'll have to see if I still have pictures of how the O2 sensors are plugged in
