Vacuum leak - listen for the hiss with the engine on or use a propane torch (unlit) with the engine running. Go around all vac connections and listen for the idle to surge (burning propane)....theres your leak.

BTW- if your car was running at 1100 previosly you probably did have a vacuum leak that just got worse or another one sprung up. Check the condition of your intake boot as well, the bottome tend to get spidery cracks in them.



Battery terminals


Do the easy stuff first
