Have you pulled the valve covers to check for any excessively loose rockers ?




Thanks.. no, I haven't yet. I'll try that tomorrow morning.

I did pull 3 of the plugs tonight to take a look at them after having it idle for a little while.. .but they all look so different, I don't know which one to use as an indicator of what's going on!

That's several photos of 3 different plugs, you can see that one of them has dark coloring on one side of the porcelain, but is clean on the other side... one of the plugs has clean porcelain all the way around, and the other is kinda tan...
