my buddys car idles from 1100-1600 and will keep bouncing back and forth like someone is playing with the throttle. Anyone have this happen before? what can be done to fix it?

 

check spark plugs n wires..? does ur friends car have any cel codes..?
when i used to start my car, the rpms would bounce around from like 500-1200 a few times, then sit at around 1100..had a cel code, map sensor, changed it, worked like a charm. this was on a 2000 ls..

 

also check for vacum leaks and or clogs my 94 had the same issue

 

check the iacv!

 

clean the iacv and the fitv, then see if its still doing it
