I recently got my ls hatch running and it idled very high like 4k and gave a code 14(iacv). I tried another know good iacv and it did the same thing and still gave the code, so i tried tapping the iacv wire at the ecu and one of the black/yellow stripe wires under the hood to see if wiring was bad and it idled at 2100 but still got the code....i cleaned the fast thermo valve and both iacvs. The ecu worked fine in my buddies integra so i ruled that out any ideas on what to try next? Im all ears lol, thanks.
