Having problems with your Cars & Trucks ?
I have a 96 dodge dakota 4-wheel drive 3.9 engine automatic pickup i have changed out one outside coil one on the outside of the motor the other underneath the rotary bug. I changed out the rotary bug distributer cap spark plug wires spark plugs three O2 censors took out the catilatic converter muffler fuel pump fuel filter cleaned out fuel injectorsand fuel rail. The timing on the scanner shows to be okay and fuel shows to be okay and everything else shows to be okay like the check engine light
Take off dist cap.turn rotor one way then the other. if the tip of the rotor moves more than 1/16 of an inch of free travel then the block bushing is worn out. the block bushing is bronze and it holds the oil pump drive shaft in perfect alignment. when worn the cam and oil drive shaft get cocked causing the oil pump drive gear teeth to wear off,sometimes cam gear is also damaged but rarely.the dist. is driven off the oil pump drive shaft and when there is exessive play it causes ignition and fuel timing problems with symtoms just like yours
