New User May 8, 2015, 10:21 AM Post #1 of 4 (1778 views) Rough Idle, Stalling, & Acceleration Hesitation Sign In 2003 Dodge Ram 1500 2WD 4.7L Engine 117,000 Miles I have replaced the spark plugs, coil packs, idle air control valve. My truck will stall mainly when I start it up for the first time in the day. It idles rough at stop lights and intermittently hesitates on acceleration. I suspect the TPS but I inspected it and it looked fine on the outside. I have been unsuccessful thus far, please assist! Thanks. Also the fuel economy has been slightly poor.

Tossing stuff is not only costly but might confuse the real problem. Just what does a good TPS really look like - just kidding but looks doesn't mean much unless it was melted or something, T sam f.

Shut off and see if it holds also. You could rule that in or out. At some point of not running properly it should throw a code. If device checking couldn't communicate it should have said that, T   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
