What exactly was done? New plugs, wires, and cap and rotor? If so, check teh firing order. Sounds like you crossed some wires.

 

more info , just exactly what did you do prior to this ? sounds like someone pulled a boo , boo . thats the best way to learn , by your own mistakes . no flame , but any day with out learning at least one new thing is a wasted day .

 

not wires yet lol ....just 2 plugs, cap and rotor lol

 

Which plugs did you change? Did you disturb anything around the distributor when you changed the cap and rotor? Are you sure the firing order is correct? It sounds like the firing order may be way off, or something was knocked loose when you were working on the car.

 

The cap can sometimes be a pain to get back on FLUSH. I would check that first.

 

I think you moved the distributor. Hit it with a timing light and see. $29.99 at Autozone, good investment if you dont have one.
