Engine missing bad under acceleration, need help.
I have 1997 f150 with the 4.6 v8 it has 110,000 miles on it. I was on my way to work today and after driving about 5 miles my truck starts to shake and miss real bad. I was running about 55 mph. As a backed off the throttle the problem would start to be less noticable, but if I start to accelerate it would come back. It did this the rest of the way to work (about another 5 miles). It didn't seem to matter what speed I was going, it would happen pretty much at any speed as long as I was accelerating. The check engine light came on and would blink whenever the engine would miss and then stay solid when ever I calmed things down by backing off of the throttle. I replaced the plugs about a year ago but it has the original plug wires in it. Any help would be greatly appreciated.
