OK, everything done to the car is in my sig, we just completed all this a few months ago and it started doing this crap a little after. Sometimes I can be driving and it runs great, and then all of a sudden it seems to just stop getting any power. It doesnt die, it just stops accelerating. Doeasn't matter if it's hot or cold, wot, part throttle, any gear and any rpm. It will do this frequently every time I drive it and it never happens at any given time. I can have the pedal to the floor and the car just doesnt move anymore and starts backfiring slightly (it doesnt always do the backfire thing and it is minor when it does) I relocated my battery to the hatch when I built my motor and I relocated all of the wiring from the engine bay to under the fender wells. I took the grounds that went directly to the battery and grounded them to the frame under the driver's fender. I think I may have a wiring/sensor issue but everything looks copesthetic. Oh yeah, I have new plugs, wires, cap&rotor, and have checked tps and even switched out my dist. and tfi module with a friend's, ,no difference. One O2 sensor is brand new, other is stock. Not sure if the map sensor could cause this. I switched my computer with a friend's a while ago and just now went to actually mount it up and I dont remember if it bolted in or not. The ground wire there is attached and the puter is just stuffed up in its little hole, it doesn't move. I'm just trying to give you guys an idea of what I have done and what I have checked and what isn't the way that ford made it. I am so desperate that I would have anal sex with a slimy-assed camel if I thought it would fix my car. Please help me out.
