First I would check the fuel pressure. If that is within spec I would run a can or two of a fuel system cleaner that works on seriously clogged or contaminated systems. BG44K is the only really good fuel sytem cleaner. You will have to go to a car dealership parts counter to get it and it costs $20 a can but two can will clean a system and get the car running right if that is indeed the problem.
