Engine Performance problem
2001 Hyundai XG300 6 cyl Front Wheel Drive Automatic 47500 miles
Engine runs rough when cold and dies out when accelerating below 2000rpm. The MAF, plugs, ignition cables and computer have been replaced. After the engine warms up it drives fairly well with slight/minor hesitation around 4000 rpm.
Any help would be very welcomed. Layed-off from work and have 2 kids in medical care.
