:banana2: I have a 1997 dakota 4x4 cc with the 3.9 and an auto tranny...Alright, now the problem- After warming up to operating temp, usually around 50mph (but can be any speed) I starts missing and knocking and skippin' around and I momentarily lose power but the truck never dies. It doesn't always happen, I can go for days without problems...I've replaced the plugs/wires/cap/rotor/hall effect, Checked the distributor for worn out bearings/bushings. Cleaned the throttle body and injectors. Replaced the Throttle Position Sensor and the Crankshaft Position Sensor. Fuel pump is fine. what do I do next?
