if you have not found the problem yet, get a can of brake cleaner (NOT CRC) or carb and choke cleaner and spray the intake and the vacuum lines to check for any leaks while the engine is running. if you find a leak you will notice a change in the idle speed. do NOT use CRC brake clean as it may eat the rubber and plastic.
