Its missing a lot and has new plugs and wires and it worked fine on the other car, also the resistance seems okay and I cleaned up all the contacts, any ideas? Maybe the engine to chasis ground?

 

Put it back on the other car and see if it still works good on the other car. Maybe its something you did on installation.

 

I don't think so because the original coil in the car did the same thing. Anyway, I can't put it back in the other car because the engine is removed and taken apart with no intent to put back together. (Its a salvage title and after finding out how much it would be for a rebuild kit and a rotor housing I changed my mind and would like to sell it for parts since I got the other one.)

 

how do you know the problem is the leading coil? if you switched them and the problem is still there then it's not the problem. the missing could be lots of things. too rich, plugs, cloged injectors...

 

I don't know that that is the problem, so I wanted to know what other things could be causing it, like maybe spark plugs not being grounded very well?
