stratman977 Posted January 3, 2014 Share Posted January 3, 2014 (edited) When I went out from work yesterday the engine light was on and it was running cold blooded. The IACV definately wasn't working. I thought the IACV was stuck so I tapped on it and nothing. When I got home I tested the wiring for the IACV with the test connectors together and it had 10+ volts. I had a spare IACV so I swaped it out and it was back to working normal. Now this morning I go out to start it and the IACV is not working again? It was below 20 yesterday and about 5F this morning but the car was in the unheated garage which may have been 20F. I just put a temperature sender in a month ago. Its a 1988 Gl Wagon with SFI. Anyone have any ideas on what to check or any experience? Maybe I just need to purchase a brand new IACV but I want to fix the issue not throw parts at it. Edited January 3, 2014 by stratman977 Link to comment Share on other sites More sharing options...
stratman977 Posted January 3, 2014 Author Share Posted January 3, 2014 I tried it again just now and at first the IACV didn't open but after about 30 seconds of chugging and sputtering the IACV opened up and the engine smoothed right out. Can you put a drop of oil in the actuator or clean them somehow or do I need to replace it? Link to comment Share on other sites More sharing options...
