If this only quits during accelleration and returns when going level or downhill/decellerating than I would blame a vacuum problem. Many vehicles use manifold vacuum for motor control of devices thru a car and upon accelleration available vacuum drops off dramatically so it's stored in a container - perhaps out of sight with a one way check valve. If that sounds like the timing for the problem than check for vacuum leaks in hose at intake manifold and follow them along to see their integrity. There may be a vacuum operated valve on inlet heater hose relying on vacuum to maintain warm/hot water(coolant) flow thru heater core. Note: vacuum lines may start at a rubber elbow and go into wiring looking harnesses as a hard plastic. If either is found broken rubber hose can patch the area and new single/universal elbows should be available. Check and hit back if you find something like that if you have trouble patching it, T   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
