I have a 99 dakota with the 318, automatic, and 4x4. When I first start it up it fires without a problem and will run in park forever. When I put it in drive it is usually fine but when I put it in reverse it will stall very quickly. It also will stall when coming to a stop. I have changed the idle motor, the throttle position sensor, both 02 sensors, the cap and rotor, and also the collant temp. sensor. I am running out of options. I've run the diagnostics test on it and didn't find any codes. I'm really getting frustrated and broke. Hopefully someone can help.
