Do a forum search... this has come up before. Take her in to the service department - I recall it was an easy fix. Don't think it is related to your headers.

Hey Slim, I had this done. It is a small pump and a few other little things that test for small leaks in your evaporative system. Took it in to the Dealer and had it fixed in 2 hours.

I did have a loose gas cap prob before I got superchips and "check engine" light came on. I took it to dealer they said the loose gas cap was cause of error code and to make sure to turn gas cap at least three clicks after refueling.

This also applies to aftermarket gas caps... they'll set a code everytime! If you want a locking gas cap, buy it at your Dodge parts counter for $20.

hey, i work in a dealer and see this code often, check for a vacume leak on the hoses coming from evap purge solenoid, but 9 out of ten is the gas cap, look for traces of rust in thecap, if so replace the cap
