Hey, ever since my pd. fire, my car has had a really high idle.... can someone suggest the easiest ways to fix the problem...

 

if u replaced everythign already....maybe u need to reset the tps

 

ah, didnt think of it... will check

 

- Set the TPS
- Adjust the thermowax
- Make sure the primary throttle plate opening is set correctly

 

Will do and post results this weekend... thanx...

 

What is the thermowax?

 

its a peice at the back of the throttle body that expands when it gets warm and closes the throttle plates a bit to bring the idle back down to normal. Do a search, I asked the same question a little while ago and someone put a pic up.

 

Thermowax adjustment has nothing to do with hunting idle. A hunting idle is becuase of 'unmetered' or unaccounted air entering the intake, and the ecu is trying to compensate for it. So as long as everything is sealed, your throttle can be halfway open and have no up-down issues.

If you had a fire, you should replace everything. Gaskets, hoses, grommets, etc, everything. All it takes is air leaking into the intake at the injector grommets, or even the throttle body elbow, etc to cause a hunting idle.

 

i still have hunting idle problems and i've spraided around inside my engine compartment and can't find a leak anywhere? is there anything else that can cause it?
