I have a 97 integra ls with an ls/vtec swap. b18b block and a b16 head. Runs good and strong. When i first got the car it would surge up and down till it warmed up then it would idle fine and steady at 800rpm, this was at the end of summer. when it got cooler it started to idle surge in neutral or any time you press the clutch in and it had really high idle. anyways i tried a new iacv because thats what the guy i bought the car from said it was the iacv. so i got another used one and it stopped surging and idled fine again well that lasted two weeks.. so now it surges all the time in neutral! and it idles at almost 2k! when i first start it tho is idles high and steady like its suppose to do but warmed up it will start surging. Ive done everything i can to try and fix this from trying different iacv's to cleaning the fitv. Any advice on what i can try will be greatly appreciated. Thank you
