So my idle has hated me for a long time, but for a while it was actaully settled down. Now it's pissed again. The second I turn on the car it jumps to 4k rpms. then in a sec it goes back down to 1 for a bit.. then back up to 4. etc..

The last time this happened I unplugged the iacv cable when the car was on, then plugged it back in with the car still on and it fixed itself. this time that doesn't work. in 20 mins i have to drive to the dentist and I really don't want to drive it broken. Any ideas would help.

Thanks

 

take it off and clean the screen out, block it off, or buy a new one

 

yeah just spray that ****** out with some brake cleaner or some ----.. what kinda motor is it? i have an obd0 b18a iacv if you need one..

 

When you pack a fresh bowl you gotta clean the screen!

 

alright.. it's a 89 hf. I pulled it off and cleaned the ---- out of it and it didn't do anything. when I tried blocking it off the car doesn't idle it just dies. Anything else to try?
