1993 Chevrolet Caprice Q&A

1993 Chevrolet Caprice Question: Why does my Chevy Caprice Classic jerk as I accelerate and as I slow to break?

It happens all the time. It acts like it doesn't want to start sometimes too. -
Answer 1
Engine misfire and warped brake rotors. (My guess.) -
Answer 2
sounds like a motor mount issue...the starting problem could be anything though...any more hints? -
