Let me know what you guys think. My issue is at idle im at 16.0 with alittle bouncy rpms but while driving its perfect 14.5-15.1

I tried closing the isc alittle bit and it did nothing. i noticed that at idle my o2's arent switching at all but obviously while driving they are fine.

My initial though was the iac is bad.

Keep in mind ford strategies are not created equal ans how the ECU determmines final fueling/spark can be different, no books capitalize on this. This is one of the bigest hurtles I see and hear from new dealers I'm training.

Try lowing your FI Low Slope and see if the idle gets any better. Another option would be to raise your Injector Offset vs Battery Voltage in he 12-15v range.

Finally tried lowering my low injector slopes.

it was at 72, i set it to 71.5 and nothing changed. You think i need to lower it more or do i have a problem with a hard part.

If the issue is that big, I'd try lowering it 5 whole numbers and see what that gets you. What is your KAMRF at 2ms and below?
