Shutup&fish Posted December 12, 2010 Share Posted December 12, 2010 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 Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted December 13, 2010 Share Posted December 13, 2010 Very Basically Thinking: I believe it has a Vacuum Leak somewhere... but it also might have a MAF sensor malfunction. Quote Link to comment Share on other sites More sharing options...
michael appel Posted December 13, 2010 Share Posted December 13, 2010 vaccum leak first but yes it sounds like iac valve could be malfunctioning mass aif flow last if it starts right away its not the mass airflow trust me I know still fighting mine Quote Link to comment Share on other sites More sharing options...
