I have a 1998 Dodge Dakota SLT 3.9 V6 Magnum with 4x4. The entire time I've owned it its missed so bad that it shakes like an earthquake. I've tried replacing all the plugs, plug wires, rotor button, distributor cap, and two of the injectors. It has a code for number 4 cylinder misfire, number 6 misfire, and a multiple cylinder misfire. Obviously, my number 4 and 6 cylinders are fouling out my plugs and not firing and the number 2 is weak. My only diagnostics are a bad PCM (the drivers), a bad ground, or a blown intake gasket. I've also seen some things about maybe a timing issue of a CKP sensor, a CMP sensor, or maybe a timing chain. If anyone has had a similar problem with a similar Magnum engine or knows what it may be let me know if you can possibly make a suggestion.
P.S. I've done a cylinder contribution test and the 4 and 6 are defiantly not firing
