I'm experiencing a hesitation while accelerating under a load. It usually occurs while I'm either in third or fourth gear at about 3000 rpms. If I let off the gas it will stop immediately. I seem to notice it more when cold, sometimes it drives perfectly. It has not thrown a CEL and doesn't have any codes stored. I've had it checked out by mechanics and they can't simulate the hesitation, but it happens to me all the time. It has new plugs, wires, and fuel filter. It also had upper and lower intake manifold gaskets replaced. I'm not sure what to try next.
