That'* why I want to use hotter spark plug.

Vas....see your pm'*.

Let'* pull the plugs on cylinder 3 and 5. Do the two compare at all or is one clean and one ugly? Burning coolant would clean the plug and it would look differently than the one next to it.

Personally..I'm starting to think PCM.

A hotter plug does not give you a hotter spark, it retains more of the heat in the plug itself. It can help in preventing carbon buildup if you do a lot of city driving, or help burning oil off from the plug. It will not help an improper mixture burn better.

If the plugs look the same..I'd doubt you were burning anything.

As Bill said, if you are getting coolant in the cylinder, that plug will look quite different from the others. The porcelain will be quite white, and the plug looking cleaner than the others.

If it'* not getting coolant in there that'* a great news for me.
I hope this is true in my case.

Bill, thank you again.

Archon, thank you for replying and great info.
