[QUOTE="DILLARD000, post: 1039696, member: 74901"] ExST Gen1 V6~4.0L~SOHC; which year 2001~2005? Suspect MAFSensor, TPSensor, IACValve, DPFESensor, EGRValve\Controller,... maybe a vacuum leak. I'd give all above a good cleaning & inspect all vacuum hoses+fittings for cracks\leaks. Do one thing at a time, then test drive 'til you've found cause. Do you have a CheckEngineLit? Have you scanned for OBD2 TroubleCodes? How old are Plugs+Wires+CoilPack? Could also be a failing FuelPump. How old is FuelFilter? Any other recent maintenance work or part changes? [/QUOTE]
