I have a 1990 5.0 Mustang that has developed a high-load, low-RPM miss. The miss is most noticable at WOT below 2000 RPM and goes away with increasing RPM. My guess is that it is ignition related. I have replaced the plugs, wires, distributor cap, rotor, coil, and the TFI module with no success. It has slowly gotten worse over time.

Any suggestions would be appreciated.

Thanks,

Jeff
