Default 1992 Ranger 4.0 engine missing

The engine keeps missing but it doesnt do it all the time. I have replaced spark plugs, wires are 2 yrs old. I have cleaned all of the wiring harness plug ends with electronics cleaner. Cleaned all of the grounds. Tested the fuel pump and pressure regulater all are within pressures changed fuel filter 2 times a little water in 1st one 2nd one was clean. Cleaned coil checked for cracks and tested its ok. Have put Sea Foam in gas the last 3 fillups to clean injectors. New MAP Sensor. Checked for Vaccum leaks cant find any. Cannot figure out what is causeing the miss. Any help would be appriciated. Thank You

Welcome to the site..

Is it a hard misfire, more of a surge or ?
Coil pack is OE?
What op range does the misfire occur at?
