Tune up help!

Tune up help!
I just bought a 1987 F150 2WD with an EFI Inline 6. The main problem with the truck was that it would die if running in park, once you put it in drive it would run fine. I figured I would start with a tune up since I didn't know when the last time I had one was and because the spark plugs were rusty. I replaced the Spark Plugs, Spark Plug wires, Rotor and CAP, Air filter, and Fuel line. I also ran some engine cleaner that the auto parts store recommended through the oil and gas. The PROBLEM is that now when accelerating the truck runs rough. It almost feels like its missing a cylinder. It feels like a slight rev then a loss of power in about half a second to 1 second intervals but not in any real order as in it will do this for a few seconds then stop for a few, when my truck gets warmed up it gets worse. So far I've checked and rechecked my spark plus, thair GAPS, spark plug wires, and firing order. The cap and Rotor seem to be installed fine. Is it possibly a fuel problem? Any help would be awesome! Thanks!

You may want to test it to see if it is OK.

The codes in the CM should be gone.
