thought I would whip in here and give an update as to my condition..

I changed the fuel filter last weekend and after that it got about a million times worse.. Infact after I did that I could barely keep the car running.. Decided that I was going to do a little investigating in areas I could not see as I swapped the damn wires and coil pack 3 times w/o success!

I started searching everywhere for a vacuum leak and all of a sudden I saw the culprit..

I must have hit a pretty nice bump and the Crankshaft position sensor wiring came out of being tucked up inside an engine cavity and fell against the serpentine belt and was rubbing.. it didn't cut it in half but it rubbed the wires completely raw in spots and I assume that it just kept getting worse with each test drive and test rev I did with the engine.

so we cut the wires and spliced it back together and then ziptied the wiring all nice, neat and tight so it cant happen again

The car runs like a goddamn top now..

Not sure if we just didn't push the wiring back on the same pegs or whatever when we rebuilt it and dropped it back into the car or this could happen to someone else with hitting bumps pretty hard -- but if anyone ever has some of the same symptoms I had its worth looking at your wiring to the crankshaft position sensor..

I hope the rest of you have figured out your running problems.

... where is it located?




From Ford CD.
Crankshaft Position Sensor
Removal
1. Disconnect battery ground cable.
2. Raise vehicle on a hoist (or jack up and put on jack stands).
3. On 2.5L engine-equipped vehicles, remove splash shield from RH front fender apron.
4. Disconnect the fuel charging wiring or engine control sensor wiring (depending upon application) from the crankshaft position sensor (CKP sensor).
5. Remove crankshaft position sensor retaining bolt and remove crankshaft position sensor.

Installation
1. Make sure crankshaft position sensor mounting surface is clean. If equipped, make sure that the crankshaft position sensor O-ring is in proper location on crankshaft position sensor.
2. CAUTION: Do not overtighten crankshaft position sensor retaining bolt or damage to the crankshaft position sensor may occur.
Position crankshaft position sensor and install retaining bolt. On 2.0L engine-equipped vehicles, tighten retaining bolt to 6-9 N-m (53-80 lb-in). On 2.5L engine-equipped vehicles, tighten retaining bolt to 8-12 N-m (71-106 lb-in).
3. Properly route fuel charging wiring or engine control sensor wiring (depending upon application) and connect electrical connector to crankshaft position sensor.
4. On 2.5L engine-equipped vehicles, install splash shield. Tighten retaining screws securely.
5. Lower vehicle.
6. Connect battery ground cable.
