Need Help

[chevysboy]

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

If the Opti is the original unit, it might be time for a new cap and rotor. Plan on a water pump at the same time.

if this engine starts ok and runs normally when cold then screws up after it heats up this is usually the EGR,,,,,this valve has a weak spring and is opening too much this will cause this issue....EGR is allowed to operate only after engine heats up....this part usually is in need of replacement after 100,ooomi...especially if operating in a hot climate...
