my engine will buck forward when driving, it will only do it after warmed up. I have thrown hundreds of dollars into this engine and would like to know whats wrong. I believe that it has something to do with the coolant system, but i could be wrong. I have replaced:thermostat, map sensor,egr valve, plugs, wires, O2 sensor, fuel pump, fuel filter, camshaft sensor, air intake gasket, ignition coil. also i have repeatedly checked the fuel injectors and vacuum lines, not leaks or problems, any ideas???
