Thanks for all the help!! I figured it out on my own, replaced a coil pack, all the plugs, and wires. Runs great now. Also , be sure when you change the plugs that you use platnium plugs, which are oem. Whoever changed the plugs last used cheapo autolite $1.39 plugs. I went with platnium which were not much more at 3.99 each. Also plan on spending about 3 hours changing the back plugs, unless you have little girl hands, and take plugs out without seeing them.
