Do you have an aftermarket throttle body? If so, I’d do a base idle reset like others have said. In my experience, these cars have the idle set way too low making the iac do all the work creating idle issues. If the throttle blade is open slightly to allow the engine to idle around 500 rpm’s or so with the iac unplugged it’s always fixed my idle issues.
