car idle

[hayashi_1986]

Yea but problem is only when its hot...
Why would it not idle hunt when its cold if its just the TB gasket..

Well thats the reason that led me to believe that it wasn't the TB gasket. It would idle fine on cold start, but as soon as it reached operating temp it would start to hunt between 1000-1500rpm. It wouldn't hurt to replace the TB gasket with a new one, as the factory ones are pretty flimsy. When I took mine off the first time, it was in tatters. It's no surprise there'd be a leak in there somewhere. The chances of your TB being cracked or sensor malfunctioning are less likely than a bung gasket. Give that a shot and see how it goes.

Cheers!

Has the throttle adjustment (screw) ever been readjusted? Perhaps you need to revert it back to its factory position.

If the idle adjustment screw has been touched, the only difference it would make is the idle would either be higher or lower obviously, but it won't affect it to a point where the idle is hunting or something has malfunctioned/failed to read something right. Though, it can sometimes trigger these sort of reactions from your comp if you suddenly adjust it not knowing that you have a bung sensor or gasket somewhere in the loop.
