My car idles well, but acceleration bogs down (hesitates). Can the iacv cause this symptom? Iacv works like the old chokes in a carb engine.
Voltage test of ecm connector A(31p) pin 12 bl/red iacv valve, reads 9 volts w/igni switch on (ii), should be ~5volts, I took iacv off car attached 12v and it does close & opens after removing 12v. So I can assume iacv is ok? Or can it still cause hesitation upon acceleration? Also, any idea what the resistant values should be between the 3 pins?
have the same problem?
