this car has been having a plagueing misfire for the better part of almost a year of ownership

its a constant miss at idle... part throttle and WOT

i have replaced...

ECT
ACT
CAP
ROTOR
PLUGS
WIRES (came with new motor, but had them replaced on old motor still did it)
COIL
TFI MODULE
DISTRIBUTER (stock one came with new motor)
BAP
02 SESNORS
TPS (stock) SET AT .96
TIMING CHAIN (double roller on new motor, came like this)
VACCUM IS ROCK STEADY AT 19lbs AT IDLE
FUEL PRESSURE REGULATOR (set at 38 vac off)
CLEANED THE IAC
DELETED EGR (and bought the EGR plug in simulator thing)
TIMING ADJUST MULTIPLE TIMES (10*, 14*, 12* nothing works)


THE WHOLE ****ING ENGINE lol (seriously i swapped out the motor that was doing it orginally with a 87GT motor and it is still doing it)

motor still does it

at idle you can hear the miss, and hte engine runs rough alot of shaking in it... then at throttle it has complete dead spots... and when its cold it will making popping noises and buck under acceleration while its in its dead spot, then it will kick out of it and just have a complete dead spot again.

any help? LOL

have driven the car while its missing and have seen the FP and Vac..

FP would raise on ACCEL and go back down while cruising...

VAC was steady doing as it was supposed to do

U sure its a miss not that it needs motor mounts? Also did you ever run the car and unplug one at a time each spark plug to see which one doesn't make a difference in the rpm of the motor. Try also a fuel filter. Where u located in new york by the way if u dont mind me asking.

Change the fuel filter? Check for codes?

Elmont... border of Queens

Yes i have changed the Fuel Filter. and i have pulled codes...

got codes saying somthing about the EGR think it is code 33

also got codes saying running lean on passanger and driver side banks.

IF motor Mounts cause the car to have dead spots and popping noises.

have you checked the injector harness for bad connections/ breakage of any wiring, usually the ford wiggle test can find such= go around and lightly tug on any and all wire harnesses and see if the issue arrises when you get to the prob area in a harness

lol i like that "ford wiggle test"

i havn't tried that but i will do it once it stops be so damn miserable here on LI, realllllllly windy

Only things i have not touched off the top of my head is

Injectors (same ones from the old motor)
Computer (i made sure it was a SD computer)

i was only saying motor mounts only because it would look like it has a miss from so much engine movement.

that is what ford actually calls it in all the troubleshooting guides = wiggle test
