Mechanic checked fuel pressure. Said it was 28 psi. Shop manual states 35-45 necessary. Bit the bullet and replaced with Ford pump. 199.00 + 50.00 labor. Not 1 bit of difference. Still falls flat on face when gas is applied hard. When I tested a different set of plugs (champions) no differnece at all.
Took it to Ford dealer and they said the fuel injectors need to be "flushed" and the spark plugs should be Motorcraft and that was thier solution. (Forgot to take the champions out)The wanted 125.00 for the flush and another 125.00 to replace 4 plugs. What a joke! I told them to flush the injection system because it sounded logical. I picked up the car and nothing changed. I pulled out of the parking lot took 5 minutes and replaced the plugs with new motorcraft and brought the car right back and said try again...................we'll see what they make up next. This repair cost me 125.00+ 89.95 diagnostic. What's next?
