when at idle my rpms sink down to almost zero and sometimes it stalls out and sometimes it bounces back to 2000 after stuttering a little bit, its been a little while since i changed the spark plugs, so that might be it. what else could it be and is it expensive to fix. thanks

 

Clean your idle air control valve

 

yes...someone has had the same problem as me! i think mine works now. has ur car ever stalled out when ur coming up to a light?? do what 02GT said use carberator cleaner that should fix the promblem i havnt had that happen to me since i did that

 

I ended up replacing my IAC. Cleaning didn't help.
