I am sorry about the length, but I figured details will only help.

Ok, so let me just give a rundown of all the basics. 97 ford xploader sport (motor was swapped, uses r12 so might be pre-97), runs rough at idle and wreaks of gas when ever on. bought the truck 2yrs ago for cheap, been fixing things as they go wrong (college kid w/ a sick mother and I pay everything). anyways today I turned the truck on (it is now florida's ver of winter) the truck acted like it wanted to shut off, so I kept my foot on the gas. Let it heat up, put it in drive and started on my way home, when I came to a stop the truck wanted to shut off.. I got onto the highway and tried to accelerate and stuck at 2k rpms and 50mph. I played with the pedal a little no change, so I tired increase slowly till the pedal was on the floor. after a few (20 maybe 30 secs) I got the higher rpms and the truck shifted, but I was coming off the highway. so as I took my foot off the gas, I saw the battery light come on. I turned the car back on (from neutral) and proceeded foward. after that the truck seemed to have hit a wall, would not go past 50 @ 2k rpms. to make things slightly more interesting I could hear the motor was suffering (more than usual, I had the codes read at a autozone once and I am miss-firing almost all 6. it has run this way for just about 2yrs+) but now there was a stronger misfire. now with the truck parked, I can rev it and things sounded as they did. though once I put it in drive and move maybe 30 feet I hear a :clunk: and it goes back to pushing the gas to floor and still going no where. lastly, there was significant smoke coming from behind (when I first pulled off the highway) I saw it through the driver side rear view (it was dark, but it looked white/grey note: I did pop the hood whe I first pulled over (had no light) but I would say moderate smoke was coming out. After I drove it from the median to the parking lot It did look like it let more smoke (this was light and I almost didn't notice) from where the coil packs sit (not directly) but I felt that is where the source must be. There is a strong burning smell (not sure, smells a little electrical). Also I did recently mix gas to likes of chevron and racetrack (majority chevron) but I did fill up at 3 gas stations recently (chevron full tank, race track quarter, and then another quarter of chevron). by the way december/january I replaced wires, plugs, and coil pack. also checked tranny, oil, and coolant they are up to par on levels.

First half of your symptoms leads me to belive it's your Fuel Pressure Regulator.


What motor? 4.0L OHV, or 4.0L SOHC?

I believe its the most common motor the 4.0 ohv. though if it was the regulator why the smell and smoke?
 






ok, so I had a friend look at the truck today, we were both a little :scratch: anyways the new info is that the smoke is coming from behind the motor. there was some tranny fluid on the ground (2 quite small stains not puddles). there is also what sounds like boiling/crackling under the truck. this was all what transpired before driving it, now I drove the truck though around my neighborhood and well it didn't start acting up till I went to put it in reverse. backed up fine but I wasn't straight so I put it in drive and then back into reverse. there was heavy surges where the truck just wanted to shut off and was shaking to do so, I could feel the loss of electrical juice. when I bent down to check under the truck, the tranny looks to be leaking but not actively leaking to where I can see it.
 






Blown front seal on the transmission. Very Common. Very cheap part. VERY trouble$ome to get to.

Your fuel smell STILL sounds like your regulator.
