1992 Dodge Dakota Q&A
1992 Dodge Dakota Question: Why is my 1992 Dakota V6 3.9 2X4 - Intermittent Stalling?
Manual shift, V6 3.9 Sport with 134K on the clock. The truck is stalling when transitioning from being under load to no load. This is happening 99% of the time at very low speeds (when turning corners). Clutch is partially depressed around catch point, no gas pedal then stall. Truck can usually be restarted with some effort. To date, and in the following order the dealer has replaced 1.) the AIS sensor with a full fuel system cleaning/throttle. 2nd time back same problem, replaced the fuel pump, the fuel filter. The 3rd time back the ASD relay. Today, after picking up from dealer and dealer saying all fixed, it stalled both when turning out of the dealership and also (for the first time) while just sitting in Neutral / idling. No codes are showing (OBD 1). Only one owner and truck has been well maintained over the years. Please help. - NIU2013
The IAC valve (intake Air control valve) attached to the throttle body is most likely plugged with carbon, or is defective. It controls the air entering the engine at idle, and during deceleration. Remove and clean it as well as the passage behind it, and reinstall, or have the dealer clean and test it. Good Luck! - lightsaber
