Stop in for a cup of coffee

Got most of my snow plowed.
Fixed buddy’s wife’s van,put the winter tires on it. Went to fix the flat, its toast. A handful of burned tire inside.
Run flat...not!
She is the destroyer of tires.
Worst one in the municipality according to the tire shop.

Buddy did his plugs on sunday, misfiring for some odd reason.
99 chev 5.3.
Scanner reveals #7 misfiring.
So pull plug. Nothing wrong.
Swap #3 out for it.
Fire truck and misfire gone.
Road test and all is good.
Plug wire was on good, had to work at it to get it off.

Dunno, is fixed.
