Put on some new headers a few days ago and now I started getting a really unstable idle and both P0151,P0131 codes. It was idling fine until I disconnected the battery while I was retorquing the header bolts today. After I reconnected the battery and fired it up its been running like crap, its fine as long as I'm moving but its the idle. Any ideas?

Some common things - Check to make sure your oxygen sensors are plugged in and that your pipes aren't in contact with the oxygen sensor wires and melting them.

Checked out the wiring and it all looked good, no pipe contact. Since the car has 75k miles and the original oxygen sensors I thought it would be a good idea to change them out. Since changing them out it's been running much better and no more oxygen sensor codes as of yet.

i think its normal, when i had the battery off the car while i was working on it.. it always had an idle problem, dont worry it will fix itself.

the codes you're getting are a package deal with headers.
