Did the DIY IAC Valve Clean and now

[freq]

when the car is at full operating temp and I come to a complete stop the car nearly dies but slowly comes up to 950 rpms (high, I know). My concern is that the car ALMOST dies and goes down to roughly 500 rpms.

Yes I did the ECU reset.

Thoughts?

mine did that, after a while it went away, my guess is that the ecu is relearning all the sensor info or something like that

Drive around for a while. The cleaning IAC is just a 50/50 fix. It can be just a dirty screen or the whole unit needs to be replaced.

oky... i have done it about month ago.. but.. maybe you should

you have to reprogram idle rpm level on the ECU...

1.just make sure you let it cool down, unplug IAC valve connector (middle of intake manifolder)

2.turn the engine on let it run until engine heats up( the fan should run at least onec or twice..)

3.adjust the thottle body screw( i think you should adjust to 550rpm +50/-50 for f22 motor, and if you have h22a like mine should be 800rpm +50/-50)

4. turn the engine off, plug the IAC valve connector

5. unplug the 7.5amp "back up" fuse(mine was red) from the front fuse box under the hood on pass.side right near the right front suspension bushing

6. wait for about 15sec plug it back on(reason for doing this BC you can reset,and reprogram your ECU with new idle rpm)

7. start the car, let it heat up...
DOne..

mine works fine now...
