i have an atrocious vacuum leak (i think i can even hear the hiss), that's raising my idle. yesterday, i tried probing some of the hoses with an unlit propane torch to see if i could detect the leak. i thought that the procedure was seeming unfruitful, so i disconnected the FPR vacuum line and put it straight to the bottle. i could not notice any difference in idle speed. i have a can of starting fluid i was about to use, but decided against it when somebody told me that there's a high likelihood of fire if i try to use it for that purpose. anyone care to recommend something else or another procedure? TIA
