my problem is when i'm over 3k and near WOT and up to WOT it will start missing. I changed the feul filter, plugs, feul pressure regulator, coil, had the TFI tested and good, ohm tested the wires and all are good. Can't find any vacuum leaks(checked with propane and also ether) Timing is good. Air filter is clean. Throttle body is clean. codes are clean just pas codes. Did the cylinder test and it was a pass. I'm out of ideas and everything else is to expensive to replace without knowing for sure if it bad or not. Also no wobble in the distributer shaft. Cap and rotor are clean and only supposed to be a year old.Check all electrical connections seem to be good but no telling though. Feul pump has a steady tone to it. Thanks for any help.
