engine intermitent miss after rebuild
 

After rebuild my 87 3.2 found intermitent miss, feels like no power like running 2 cylinder, suddenly power come back, already change speed and reference sensor,also CHT sensor, try both Steve Wong chips and factory chips no luck, also get a 88 DME from a friend, also no luck, clean all the ground, still no luck, can any fellow pelican tell me which ground related to dme is it in tranny main ground or in intake runner #1 , also check spark plug gap 0.7mm and reference gap 0.8mm, please help, also when the car warm runs better than cold, and sometime run over potholes car miss again, any input welcome. thanks.

thanks Andy fuel injector also clean and balance, new fuel pump, filter, coil, rotor, caps . only the fuel pressure I havn't check yet.

I would look at the fuel injector bulkhead connector. If it's loose, then replace.

Bulkhead connector is it mounted on rear shock tower yes it is loose, where I can buy this male female connector ? Thx

You can replace it with a 4-pin weatherpak... Lordco stocks'em.
