Running w/o IAC

[Cuska]

I have a bad Idle Air Control, my X will stall out at low RPM some times, other times it runs fine though. I'm stuck at my parents place and gota take a ferry then drive to Vancouver in heavy Olympic traffic.

During trouble shooting i noticed it idles ok with the IAC unpluged. Would i damage the truck if i ran it at highway speeds with the IAC unpluged from power? just to prevent the truck from stalling when traffic comes to a halt.


comments please

Did you try to clean it?

Yes i have cleaned the IAC. (usually do it every 4 - 6 months cuz it gets dirty behind a K&N) took it to the shop i used to work at and the lead tech told me it had finally died

I guess it's time to replace it. You should be able to get this part at any local auto parts store.

The iac is just a valve that lets air in when the throttle plate is closed, so once its open that valve is no longer used, it wont hurt to run with it unplugged.

It should not be able to run with the IAC unplugged. It should die almost immediately. If it continues to idle, you've got another vacuum leak somewhere.

that isn't true..

when you open the throttle plates the IAC opens FULLY to 100% duty cycle.
it does this for a reason.

So when you lift your foot of the throttle, the engine doesn't stall.

Pfff... don't worry about it, i've been driving for a year now with a completly shot IAC. use to keep idle for a couple of minutes when cold but now no matter how cold it is my idle drops to 0, but it didn't cause any issue to my engine, still runing strong with 135k miles, bad thermostat (and let's not ask when was my last oil change...). It's a pretty cheap fix you should do it, if not you can still drive it just learn to find quickly your sweet spot on your pedal to keep idle around 800 while braking.

Pfff... don't worry about it,

that is always another option
