1994 GMC Safari, 4.3L V6 EFI 180500 miles
I replaced the IACV with a new one. Now the engine idles aprox 2000 rpm. Followed the "RESET PROCESS" (Operate vehicle @ norm eng temp at 40mph. The ECM will command the IACV pintle to mate and proper idle regulation should now result) It didn't!
I cleaned the old IACV and reinstalled and I've a better idle but not smooth.
