How's the ground strap between your engine and frame? If it looks decent, you might still want to try backing out the bolt, then driving it back in. That's a lot of unique failures happening all at once.

This is a good thought. Any time the electrical shit is flipping out in really crazy ways it's usually a grounding problem.

I just had a weird problem with my Ecoboost F-150. First I was getting a misfire but replacing that coil (the same coil had gone bad a couple of years earlier) cleared that up. Then it started doing something where it would suddenly have no power and go into limp mode. You could floor the gas pedal and it wouldn't go above an idle. Turn the engine off and back on and everything would be fine. It happened 3 times with months between them so I figured I'd just wait for it to get worse. It did a little bit but it still only happened 3 times in maybe a month. Last couple times it threw codes about catalyst efficiency and turbo under boost. Took it in to a shop and they drove it to lunch for a week and never got it to act up but the guy seemed pretty confident that the problem was the throttle body. He says he replaces 3 or 4 a month on Ford pickups for similar symptoms and it will hardly ever throw a code. A week and $485 later it hasn't happened again, but since it was already so intermittent who knows. Hoping for the best.

I get parts from Rock Auto. They have a large range of parts depending on whether you want economy, OEM Equivalent, or performance. My buddy that's a mechanic tells me that their prices are pretty much the same as he pays for parts. They charge quite a bit for shipping though, so keep that in mind when you're comparing prices. I don't know if it's because I'm in the sticks but the parts stores are very high priced and have very little selection around here.
