lt1 idle problems

Im new to this whole website, but I figured I'd go ahead and post my first problem. My 1995 Camaro Lt1 z28 is idling in park around 1400 and 1500 rpms. In gear it's idling around 900 rpms. Please help because my car doesnt rumble anymore because of this high idle and my car is jerking everytime i put it in drive because of the rpms. please help any suggestions.

and ive already put the idle screw all the way down and it is still idling high. computer problems possibly? help please

Well, you're not supposed to mess with the idle screw because now you need a tech tool from a dealer to properly reset the idle when you find the cause.

You either have a vacuum leak or a dirty or failed Idle Air Control Valve,
( IAC ), or you simply needed to do an idle relearn.

Do you have a SES light?

I fixed this a few months ago- for me all it took was a new IAC. cleaned the throttle body while i was at it- good to go in about 30 mins.

I would rule out vac leaks first then try that. worst case take it back to autozone.
