    leaking fuel regulater or leaking fuel injector. Gotta have fuel to sputter. Ignition source is nothing more than residual heat and compression.

    He pulled the kit off Casey, that's why the stock plugs are back in it.

    Thanks !!! I am driving and reading on my phone so I didn't catch all that !! I hate stock plugs either way and I think is a nightmare if the motor has. Big cam with a good tune and then go back to stock plugs ... Sorry I will watch the road Now and tr6. In everything I do
