Hey there folks. Got bored in the fall and decided to change my valve cover gaskets. Easy enough process, right? Since I needed to remove all of the \"stuff\" to get to the valve covers I figured I would change the thermostat and the water pump for giggles, just because it was there. I put everything back together and fired it up. I crossed two wires and shut it back down. I developed a miss after that and then ordered a new coil pack, wire, and plugs (all Motorcraft). Ran great, for a while. Was traveling with the wife to the movies one night when the truck seemed to turn off at 45 mph. No notice, no engine lights, no noise, nothing. Whipped off to the side of the road and as I slowed down the truck just fired right back up as if nothing had happened. It did it a second time that night and I got her home and parked it (it isn't my DD and winter was coming). I did drive it to work one more time after this happened. On the way home it bogged down, wouldn't idle, and could barely get it to move under power. If I shut it down, it would fire back up and run, not great, but I got it home and parked it for the winter. It is decent enough to drive around now, but it is definitely not driving well at all.

Here are the KOEO codes that I got tonight: 159, 159, 114, 157

My KOER codes that I got tonight are: 412, 116, 159, 312, 116, 159

Here is where I can use a little help. I found a site called \"easyautodiagnostics\" and checked out the MAF, and the TPS and they seem to be working properly (according to following the directions on how to check them). I have 34# of fuel pressure at KOEO (i did not see anything leak down while it was hooked up) but I did not check at KOER. Also, I haven't double checked to make sure that I am firing on all cylinders (hopefully when I have a second person around). When it does fire up it runs very poorly; I have black crap shooting out my exhaust. I am able to put parts into my truck if needed so that isn't an issue, but still, if the part is good why replace it? If i am missing other diagnostic areas, I am open for the help. A little guidance to check other things out would be awesome. Thanks in advance for the help!
