Very clean tables, I might need to clean mine up some more I have a lot of decimals just from using percentages to raise or lower areas.

Put new plugs in this morning and it fired right up as it should, it did not seem to help with the low speed bucking at all tho. Gonna check wires when I get home and make sure everything is as it should be. I’ve had wires pop off in the past and be down a cylinder and barely be able to tell until the check engine light came on.

I noticed a slight miss on avalanche in wet weather, before I did the refresh. Popped the hood to spray some water on the coil packs and noticed an arc. Plug wire wasnt even connected to the coil, just close enough to arc. I couldn't believe it was still running like it was

Only by luck and sometimes, the grace of god. Oh, and with a lot of help from my broski who I won't name

I was just going to mist some water from a spray bottle and see if anything arced or it started missing. I was getting the garden hose out...

I was just discussing with my Tahoe Twin yesterday how the "old school" copper plugs were actually better performers, but last about 100K miles less. It's got me thinking that I'd probably be a good candidate for some copper plugs with how mine's tuned and with how little I drive it. I'm glad you shared the details. I've been trying to find something unnecessary to spend money on.

*EDIT* NGK #42-TR6? #4177?

Let us know the horsepower and mpg differences if you do this. I was thinking along the same lines earlier this year.

You have hoes in your garden? I could use some hoes.
