View Full Version : Cold engine misfire.

I've getting misfires now that it's been getting colder. But just when my motor is cold. I recently switched to NGK BKR7E's. I'm thinking that the colder heat range plug is causing the problem. I was thinking of switching back to BKR6E's. Any thoughts?

Yes if you live where it gets really cold during the winter you want to switch back to a hotter plug.
