Misfire and idle problems

afattitude · 11-06-2009, 05:49 PM

I have had problems with backfiring at low rpm under load and a slight miss at idle ever since I did the EGR/AIR delete. What should I start looking at? Wires possibly?
2000 Trans Am M6

EGR/AIR delete, Lid, full exhaust w/ LT

I just got HPtuners and started to try to remove the EGR and AIR from the PCM. But maybe I didn't do it right?? Other than that not anything major ex. timing tables, spark, fuel etc...

Is your Service Engine Soon light on with codes for EGR and AIR??

I'm assuming you used block off plates on the intake and exhaust to close up the ports...
