HELP Service Engine Soon Light
So is this 0420 error bad? How does the ecu adjust? Does the car start running really rich, because I did a full tank with the code on, just 3 days, but my mpg is down a ton. Usually I get 340 miles before the light goes on, and I only got 230, and I wasn't racing or sitting in traffic.

ap-evo83 how long did you have your setup on before you got the 420i error? Was it on for months?
