Still around, just don't do much posting anymore since I don't have much time or money due to the X's problems and my baby being born in Jan. So the X has become my second priority, but would still like to get it fixed.
I still have my X and it still has it's problem.
I've been replacing items as needed, which are suspect. Still no resolution though. The X has been to 8 shops for diagnosis, as well as a couple mechanic friends have taken a look. Most independent shops have pointed at the FPR, while Ford hasn't found any problems (or so they say). They basically say it's getting old and to buy new. Trans shops have concluded this isn't the problem area. The X isn't tripping the CEL, so many shops won't even look at it.
The only time the CEL was tripped, was when this problem initially started back in July 2002. Scanned and determined to be a bad #4 plug. Since then the CEL has not come back on and the X has had this Power Loss/Acceleration issue.
I've replaced the following parts so far: FPR (twice), 8 plugs & wires (plugs twice), PCV, IAC, T-Stat, EGR, Fuel Filter, all 4 O2's, Belt, both Front Hub Bearing Assemblies, Front & Rear Disc Brakes and the Hub Dust Seals (twice).
I have a K&N Air Filter, which has been cleaned a couple times. MAF/MAS is been cleaned twice (once by myself & once by Ford). System has been scanned and no stored codes. Tires rotated & balanced, alignment checked and ok.
I have a DPFE and ECT that I am looking at replacing. Also, one of the pullies or the tensioner is starting to squeal, so there goes a little more $$$ towards the X.
Damn Darkfox, guy goes and buys a Chevy. At least I'm looking at buying another Ford, maybe just not another X. Darkfox and I spoke about our problems on this as well as another message board for almost a year. Neither us of could find the problem, nor could any mechanic we knew or took it to.
Love my X, it's just starting to wear on me. Had a trip in the mountains the other day (living in CO) and damn did it suck. This thing used to fly up the mountains, now I'm almost flooring it to get up with 1st Gen Explorers and 1st Gen Pathfinders passing me up.
What ever it is, I do know it plays with the Tach. My RPM's are never high enough for the amount of throttle I'm giving the X, and at times the RPM's will slowly drop while I'm trying to accelerate. Sometimes it acts worse than others, but when it's acting bad, man is it bad.
Any questions let me know and I'll give any feed back on my experience. But I'm sorry to say I do not have a resolution to the problem. Wish I at least knew what it was, even if it was a load of $$$. Then I could look at either fixing it or selling it. Right now I like the truck and want to keep it, just tired of this nagging issue.
