My car has a hard time idioling back down. If im casualy driving and push in my clutch my rpms go up to around 2. When i come to a stop it takes a sec for my car to idiol back down. Anyone know my problem?

Both my cars used to do that when they were cold. I think the throttle blade just sticks open for a bit until it warms up, either way, I wouldn't worry about it.

Hey man, you could have a vacuum leak, thats usually what cause high idling. But a sticking throttle blade could certainly do it too. But if this has not been doing it and just started all of a sudden, I'd look toward a bad IAC valve or a vacuum leak.

I would think that a throttle blade would start to stick AFTER it warms up, not before, because things expand when they get hotter. But who knows.

You could also have corrosion somewhere in the throttle cable making it bind up. Look at the spring at the throttle body, maybe spray that whole mechanism with some WD-40.

....and "bro" is not a word.......just kidding

More information would be helpful. Is it modified?

The spring is a rotating coil type not a compression type spring, its mounted perpendicular to the throttle cable. About 1.5" in diameter. I circled it in red in the picture.
Just a long shot with that, as they could lose their tension over time and not fully close the throttle blade when you take you foot off the pedal.

But any time an engine increases in RPM, air has to be getting into the heads/cylinders somehow. IAC valve, vacuum leak via a vaccum hose, throttle blade not fully closed, rip in a bellows/hose, loose clamp on TB bellows/hoses, loose intake, crack in the intake, etc.....
