caprice has hesitation

I have a 1994 Chevy Caprice Classic LS with a 4.3 V8 engine. The Odometer reading is 196,000. Only thing ever changed as long as I had this car was spark plugs,wires, and fuel pump. When I pull off it has a bad hesitation . On early mornings when I pull off it is ok for about 1 or 2 miles down the road. After that occurs thats when it starts the hesitation, and as it starts that I almost have to hold it to the floor to pick up speed. When I am at normal cruising at about 50 to 60 miles per hour thats when the hesitation also occurs even in a lower gear I still feel the hesitation. Need immediate help on what can be causing this.

Thanks, chevysboy

More Info.

It's like telling a doctor you have a pain but nothing else.

We cannot help unless you provide more info! What is your car? What engine? All that stuff is needed.

Sounds like an Optispark failure.

BTW next time, it's easier for all followers of a thread if you just make another post with info instead of editing your first post. :P
