Hope you guys can help me out, I was driving doing about 60 and all of sudden it was like my truck got an extra shot of fuel. I took my foot off the pedal and continued to accelerate to 65. I pulled to the side of the road and putted home doing about 20-25 still not touching the pedal. The motor surges and pours out black smoke, which it never does. Usually just some white smoke on start up. I shut it off let it sit for a while started it back up and it revved up to about 3000 rpm then decreased and proceeded to bounce from 500-1000 rpm still pouring black smoke out the tail pipe. I still had no pedal response either, didn’t matter if I held it to the floor or pumped the pedal it didn’t make a difference. It could be the pmd I haven’t tried a different on yet but this one has never once given me problems in the2 years I’ve had it.
