97' 4.2l V6 running rough
Hi im new here and need help with a problem.
Recently I have noticed after driving a few miles and coming to a stop my truck will begin to vibrate and when I go to accelerate the truck shakes violentlyan acts like it dosent want to go but when I get up to about 35 mph it stops. This problem dosent happen everytime like yesterday I drove 8 miles and came to a red light and the truck began to vibrate with a violent acceleration but when I came to another stop it did one vibration and stopped.

Glad to have you here and sorry to hear about your truck.
Few questions:
How many miles on it?
Ever have to add any coolant/water to radiator?
Does the CEL come on?
Did it just start suddenly or slowly get worse over time?
Ever change the plugs and plug wires?
Have you checked for a vacuum leak (cracked or loose vac line)?
Does it occur only under acceleration? Idles fine when you pull to a stop?
