Hey guys..... I got a 420 code (bad precat, bank 2) a while back (like months ago). I just have not had the money or the time to change/gutt the precats....basically i work about 50-60 hours a week.
If you guys had to guess or estimate, how much of a power loss and fuel economy loss am i getting.....its been since about march of this year.....i know its bad.....but im on a tight buget and time frame.
