So I changed the sparkplugs and it turned on beautifully but once I put it in drive and pressed the gas it had trouble going 15mph
Also it revs in park and in drive it doesn't.

Do you have COP or coil packs? If you have coil packs maybe you bumped the input to one of the two (or both) coil packs loose. On mine, the little retaining clips on the outside of the plug housing both broke when I changed them a few years ago... Check the coil packs according to the service manual witha multi meter, you may have a bad one. Also, verify that the boot are ALL ThE WAY seated on the plugs.

I had a '94 Explorer with a single coil pack for the 4.0, when the coil pack went bad, the engine would start and idle fine, and I could even rev the engine in neutral, but once I put a load on the engine I could BARELY go past 30 MPH.

Does it idle in park or neutral?

This was discussed in another thread, since you got the code for #8 cylinder, you could try swapping that cop with say #1 cylinder cop and see if you get the same code only for the #1.

You sure you didn't bump lose a vacuum line or something? Getting fuel pressure? Are your cops two pieces? If so, make sure they're all securely connected together. I'd start checking EVERYTHING since it got put back together with loose parts, what else could be loose?

The picture is awesome, lol. Passenger side front, looks gold on your pic would be number one. Work your way back to the rear of the engine is two and three, the very back passenger side is number four.

Move to the drivers side, the front, clear on your pic is number five. Again working back to the read is six and seven, the very back drivers side is eight.

There is another pic on here ill try and find for you.
