jumping engine

i have a 95 chevy s10 4x4 with standard transmission. when i accelerate in each gear i feel the front of my truck "jumping or rocking". what the heck could this be? bad engine mounts maybe? 4.3 engine needs a tune-up possibly? help me!

We can't give you much help if you don't help us.

1) Which 4.3? There were 2 in this year.

2) When was the last time it saw any maintenance?

3) Is the check engine light on? Even if it's not, go to Autozone and have them pull any trouble codes.

etc, etc, etc, etc, etc, etc.

the motor is a 4.3 tbi. hasnt had a tune up for some years now. oil has been changed regularly using synthetic. i did change the pcv valve, and air filter recently.maybe the gas filter needs to be replaced? check engine light is not on.

Replace all the filters and give it a complete tuneup. Start there first and see what that nets you .

problem solved!! : the coil wire was loose. the end that plugs into the ignition coil was loose. once i pushed it back into the coil i took the truck for the drive and no more jumping. i am so happy!!
