Dericks, there is not enough information to give you a definite answer. this could be caused by many parts, from fuel deliver to bad filter to clogged jets. It could also be vacuum leaks, ignition issues and many things in between. what have you tried and what have you checked? when does it do the jerking?

Dericks, sounds like you are saying that it did okay with your friends distributor. Then you replaced the rotor but kept your old distributor cap. I would suggest that you replace the cap as well. Also consider new spark plugs and spark plug wires.

I have the answer, mine did the same for months on end, I replaced every filter, plug and wire and air flow things I could think of and in the end it was only the engine speed sensor that had to be replaced. Once that was done she drives like a dream again.....
