for the past 2 months i have been running the afc hack with 450cc injectors and running 5 psi ,my afc settings were -40 from 1000-3000 and -37 from 4000-7000. Then decided to hook my mbc and run 8psi with the same settings since i was running rich, then I threw a rinning to lean in bank one code. I was wondering if this had happened to anyone before?? and all so throwing random mis-fire codes in cyl.1,2,3,4

 

ug? You do have an I-4 right? Which equals 1 bank of cylinders. Check your plug wires and your plugs if you haven't already.

 

yes, could plug wires cause mis-fire? a buddy and I have the same prob. and we both have msd wires.

 

My brother had a misfire in cyl. 4 on his vr6. Turned out the plug wire wasn't seated correctly. Are your plugs gaped correctly?

 

yes to factory spec.

 

have u set your in/out to 6??

 

yes but there is some settings on my afc like dec air and some other features that i have no clue what they do, any ideas??
