wow, none of those parts had anything to do with the issue. i would look at fuel pressure. if the pressure is low when it is hot, then yes, it could be a fuel delivery issue. have a shop verify it before throwing more parts at it that have nothing to do with the repair. Roy

FUEL HAS PRESSURE.PARTS ARE FROM CODES COMING FROM COMPUTER DIAGNOSTICS. CAR IS IN SHOP!! CAR HAS BEEN TO 3 SHOPS!!

you may have pressure but what is the pressure?? code numbers never identify failed parts, just failed systems. I hope the parts replaced were from an actual diag, not just the codes. hard to believe that 3 shops cannot figure this out. it is a somewhat common issue with low fuel pressure. Roy
