So i have a 1992 legacy 2.2l motor swapped into my 1986 Gl. Cant get it to idle down it wants to be at like 2000 rpm and its not the ect sensor. And i have also notices the gas mileage is not what it should be. I tried rolling the IAC Control counter clock wise to slow the idle as a last resort....it didnt like that. Because once it got warm it would drop under a 1000 rpm. And ideas would really help
