IAC valve "idle air control", check your timing, do a tune up "plugs cap rotor coil" IAC can be cleaned with carb cleaner

if its a constant 3k idle yes id look at vaccum, but in this guys case if its jsut rough idle id say start with IAC and check voltage on tps while your at it

ahh see im learnin slowly

Yeah I had a similar problem with my car, and took some carb cleaner and cleaned out the IAC. Maybe I was lucky, but it fixed my cars idle.

definitely check for vacuum leaks
