I have a 2003 Dodge Caravan SE 3.3 L Vin code 3.A few months ago the fuel pump died. Had a new one installed along with a new fuel filter. A week or so after that it starts hesitating spitting sputtering and jerking like it's misfiring when you take off from a stop only when it is hot. I am a mechanic by trade but this is out of my league. I have replaced every sensor, plugs, wires, coil pack, cleaned the throttle plate. Repaired the injector wiring. Had the catalytic converter checked, muffler replaced and nothing has solved the problem can anyone help with this problem.
