The car is idling so fast that I have difficulty coming to a stop. It is idling at between 2000 and 3000 RPM. It used to idle at just under 1000 RPM before a mechanic replace one of the vacuum hoses. It is maintaining this idling speed and will not drop back down to around 1000 RPM. If I press the accelerator it get worst without dropping back. Could the problem be some type of sensor problem?

T 1dodge1mopar User Aug 6, 2007, 5:56 PM Post #3 of 4 (1277 views) Re: Idling problem Sign In take your car to a good mechanic and have him check the vacumn hose connections. it sounds like you have a vac hose loose or not connected correctly, causing an erroneous vac signal. the easy solution is, if you have the knowledge, is to back off on the carb adjusting screw/throttle adjusting screw on the throttle linkage on FI engines. another possibility is that your engine might have been timed with the vac hose off the distributor and not replaced after timing and someone working on your engine hooked up all vac hoses correctly in finalizing their work causing an increased idle. thomas74 User Sep 3, 2007, 2:19 PM Post #4 of 4 (1248 views) Re: Idling problem Sign In take some spray and spray roud ur engine if it phase it the u know it is a vaccum leak i like using propane it is better but carb spray will work does sound like a vaccume leak   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
