Ok please help my idle won't stop hopping it goes from 1500-2200 and back to 1500 and back up over and over... i got a new o2 sensor new alternator new starter and a 10:1 motor... i have no more vaccum leaks *** i checked them all... what else could it be???? and the maf is connected right too... HELPPPPPP ME

could be the idle air control valve(IAC)

Mine did this when I put a cai. Adjusting the tps helped.

Remove, clean and test your IACV and air regulator. Also clean your throttle body. Make sure your EGR and BPT stuff work.
