Only advice is if you buy an Accufab, which I do recommend, they don't come with the TPS - you have to transfer from your old one. Easy enough, but Ford used thread lock on the screws which can make it a challenge. Secure the TB in a Workmate or vise (between two wood blocks) or something so you can bear down on the screws without the TB itself turning. Then get your best screwdriver and bear down and crank on it, avoiding stripping at all costs. Mine we really not too hard, but I was prepared for the fight! I guess it depends on how old the TB is and how long it has soaked up the engine heat to form a nice, firm bond. Again, regardless of this minor challenge, I highly recommend the Accufab TB (and their plenum)...Quality always costs a little more, but once it's in your hands you'll understand why. They make nice stuff.
It's real easy but one thing I had a problem with: the throttle cable you have to unwrap around the little spindle it locks into but the cruise control cable you DON'T have to unwrap around--I tried it this way for a long time before I realized it just pops up and off the knob it's snap-locked over.
I just pent the $45 and bought a new tps from the dealer. It was a son of a bitch to get it off the stocker and I ended up getting so frustrated cause it wouldnt come off. Just buy a new one, much easier.
Nice car snkchmr, but man, that website has pop-up ads galore! Anyway, as I stated before, I had no problem removing the TPS from the old TB. I'd try it before just going out and spending more money buying another one...Just my 2 cents.
