Ongoing dilema!!!

Okay, Car runs bad still.

It does this: Feels like it drops a cylinder when I make the car move. Doesnt when I am in the driveway at idle or revving. When I am going down the road and it messes up I can rev it and it seems to clean up until I drive again???

I ran codes and got #14 engine off and nothing much engine on. checked fuel pressure and got 40 lbs on the nose with engine off and only about 34 lbs at idle.

Things I have replaced/checked: Autolite plugs, motorcraft wires, New fuel pump, fuel filter, fuel pressure regulator, cap, rotor, TPS sensor, ECT sensor, checked all hoses, and even swapped distributors from a good running mustang.

Car runs good in driveway but bad when I drive it. I have a vam coming to try next.

Also I bypassed the fuel pump relay and wired it to a switch because the store didnt have one when I needed it and I couldnt wait. This shouldnt matter though.

Does anyone have any other ideas for me to try?

try pulling the vaccuum hose from the EGR valve and see if that makes a difference while driving...if it does replace the EGR valve if not...go back over ALL the vaccum hoses and the hoses from turbo to throttle body just to be sure...it is possible to roll the hoses to the TB and not know it so look and feel very carefully...same as the hoses from the VAF to the inlet on the turbo...let us know what you find...

Did the code 14 come during the 1st part of the KOEO or the second part- Continous Memory codes?

Then erase the CM codes and pull codes again.
Did you get an "11" for the first part?

1 or 11 for the first set of codes.
