When I'm sitting at a stop the cars rpm drops ever so slightly then goes back up. Acts like it is going to stall. Also while driving the coolant light comes on then off. I had the throttle body and collecters cleaned and it hasn't fixed it. ANY IDEAS????

Clean out your IAC (Idle Air Controller). Spray some carb cleaner in it to get most of the junk out. That will probably help the idle issues. As for the coolant light, have you checked your coolant level?
