I installed some new plug wires and my car misfires. I have been having trouble with the wires and even cut off the grounding strap. I think their may be an internal short. It misfires with these new ones but runs fine with the old ones. I installed them correctly and it runs lean( I believe) with the new ones.

here a video:

Betcha got a wire attached to the wrong plug.

Or an issue with the dist cap/rotor.

it runs fine with the old wires. And I know they are correct and have checked them many times.

heres a video of it running with the old wires

are the new ones the same brand of wires? Did you replace the plugs at the same time? Did y7ou remove the dist cap, or rotor during your work?

If you have an ohm meter check each wire to see which one is bad. Or run the motor with one wire removed at a time to find the culprit.

just use the old ones and return the new ones
