Answer 1
Run engine at night with hood up and look for secondary ignition sparks(plug wires, coil , dist cap) or you can spray water from a bottle while idiling and see if it runs rough -

I replaced the coil pack, no distributor on my model.Runs way better, still a little rough.Next will be a tune up. -
