Hello All, I was hoping to get some advice, just installed my mopar long tube headers on sunday and immediately upon initial start the engine malfunction light came on, what is the reason for this and how can I resolve it, thanks in advance. scott
If it turns out to be just a P0420 or P0430 (Catalyst Efficiency Below Threshold) then your options to try to get rid of it are either a mechanical or electical O2 simulator at this point. I'm hoping that one of the tuning companies can help us out in the future by deleting the rear O2s like was done with the LS1 edit software.
