i keep replacing the fuel filter, once 6 months ago, and 2 more times the last 2 weeks, and using injector cleaner, but i still am
bucking like a horse and stalling
You need to determine if fuel is your problem-have the pressure tested at the fuel rail to see if it is within specifications with regard to PSI. Once you establish it is good, look for an ignition problem-bad coils, wires, distributor cap (you do not mention which engine you have , the 3.4 or the 3.8)-your problem really sounds like an ignition problem and it could be anything mentioned plus a failing crank sensor or cam sensor-check pressure first to determine if it is good, if so, start with a good tuneup including replacing plugs, the wires and maybe coil packs/distributor cap/rotor, clean the connectors at the crank sensor and cam sensor. Check the connection at the MAP sensor too, you never know...
