I switched my car from the old JB3 to MHD 2+ a few days ago. The car has been running great but then this morning I left it idiling for a few minutes and then found the SES light on pulled the codes and it was 29E0 and 29E1 both mixture control codes. I changed the coils and plugs probably not even 500 miles ago and the injectors were done by the PO. My rail pressure looks good but on a short 2nd gear log (didnt have time today to do a few WOT 3rd logs) the stft of both cylinders goes all the way to -34 which obviously isn't good. So my question is could this possibly be caused by the post cat O2 sensors being switched? I was being dumb when I installed the DPs and took the O2s out at the same time, but was 95% sure I plugged them back in correctly. The only other thing would be that some times my idle will fluctuate a little maybe 100-150rpm. Someone also suggested resetting the adaptations before anything, should I try that first?
