Hi am new to site and having problems with motor. To give you a run down someone else replaced plugs, thermostat, changed oil said was running bad at low and high speeds. I checked low pressure fuel pump, was bad replaced, decided to go ahead and replace high pressur pump. Put back together, idles fine but no top end, lot of white smoke and runs like bad plugs just spits and sputters. Does anyone have any idea what could cause this, thanks for any help.
