eeloutI have a 04 dodge 3/4 ton 6spd, when idleing, the motor will clatter every couple minutes. When taking off, motor wants to die. When clutched in, motor will rev up, then you can take off. Also runs rough in traffic but running normal on open road. Have changed lift pump, injector pump, new fuel filter, and clutch fan. Had bullydog pup on truck, but took it off to see if that was the prob. Can someone please tell me what they think is wrong?
