Yeah, you're right. They are worse on the other side. I just replaced the gasket a few months back.

They are gapped at 0.60", which is what the gap is for the California models. However, when I first did a tune up after the buying the truck, the spark plugs that were already in the truck were gapped at about 0.50". Should I try for a smaller gap?


Also, I mentioned in a earlier post that I saw slight white smoke coming out of the passenger-side of the truck a few days back. It occurred a couple of minutes after I turned it off. Could that be related to the spark plug fouling issue?




Thanks for the continued help!
