was good, i just recently did an ls-v proj. on my 94 teg. it didn't act up at first, but all of a sudden my car is idling at damn near 2.5 grand or if not that fluctuating between 2.5 grand and normal idle...(going up and down as if i didn't have antifreeze), theres antifreeze in the reseviour though. it's not the idle screw, because whenever iv'e driven the car and start it back up again, it idles normally until i start actually driving again....then it goes crazy. i was told that my throttle body could be bad (i am using an ls throttle body on a skunk2 gsr manifold, i don think it makes a difference), but i rode around with out an intake for a while and visually the throttle body looked closed and alright, how do these things go bad IF mines is bad? somebody help! i amost feel like im bout to break my motor cuz of this ****, its still kinda cold outside!

 

Your IACV is most likely dirty and sticking.

 

wtf is that? is it easy to clean or replace?

 

The IACV is the idle air control valve. It is located on the back of the intake manifold. You can clean it on the car by finding the appropriate port in the throttle body that is drawing air at idle. Spray carburetor cleaner in that hole while the car is running. This draws the cleaner through the IACV. You can also remove it and soak it.

The IACV is part 21.



It is simply an electrically controlled plunger that lets in air for idle.

 

well explained man! thanx, ima def. look into that.

 

i have 92 ls i have the same problem i changed my iacv and nothing unplug ur throttle body and see if it stops mine did so i took out my throttle body and cleaned it and it looked fine but wat wass bad was the sencer on it so i got a new throttle body and its fine now try that and c

It sounds like it is not fully clean. How did you clean it? Did you reset the ECU?

 

with brake cleaner. used pretty much the hole can but did not reset the ecu.

 

i had the same problem after not driving my car for a while i had coolant in the resevoir also but after a short time after start i had idle bounce turned out i had forgoten to put coolant in the RADIATOR! duh

 

Umm you need to take the IACV fully apart, so when you take the valve off, unscrew the plastic cover/tensioner for the spring inside the IACV housing. Throw it all in a bucket of simple green or clean it with brake cleaner, rinse it out, put it back together (tightly, because putting it together loose usually fingerbangs the idle as badly as it not being cleaned at all) and reinstall. Also, the FITV (fast idle thermo valve) usually creates similar problems as the IACV, its located directly under the throttle body on an LS if I remember correctly, in a harder to reach location than the IACV, and you clean it in a similar way. Hope this helps
