Hey black 1987, i figured out the problem myself. it turned out to be a bad coil. it was not firing out of 1 cylinder. Got A new one for $25 shipped the next day off ebay. Works perfect!!!!
Head up for any who may be reading this. Cause i trusted my mechanic as i have been going to him for years. He said it was the valve and would cost $1200. I said, "i went to a ford ranger forum, and everyone was telling me to check the coil, plugs, wire, ignition." He said it wasnt my coil but didnt even check it for spraks.
BOTTOM LINE: iTS good to have a site like this.
