Starting troubles
I have a 2000 4.0L 4x4.....Truck starts rough....chugs.....seems like it wants to die....then all of a sudden idles fine....its like something is stuck somewhere.....and then its gets through....This has been an ongoing problem.
Last October I replaced the fuel pump and fuel filter.....then i replaced the IAC motor.....and maf sensor.... still starts rough....dont know if a vacuum line would do that or makybe something with the radiator. if anyone has an idea let me know....thanks!

Welcome to FTE!
Is it possible that maybe something is leaking down into the cylinders while the truck sits? This would cause the intial choking and stumbling while the stuff is being burned off.
A bad injector leaking fuel, or even a lower intake gasket that is allowing coolant into the cylinders, can do this.
