WTF spark plugs!

I've been running with AL103s for a few months since I dropped to the 3.1 pulley, back then I kept the TR6 plugs that I was using with the 3.25 pulley since I only used them for a couple of months.

Now I switched back to the 3.25 but kept the AL103s. Today I decided to take out the TR6s that I kept and put them on, but when I turned on the engine, it started miss firing a lot.

After a lot of tests with the wires and what not, I decided to switch back to the AL103s for now, but to my surprise it was also miss firing!!!

All plugs have been used for a few months and are not damaged lol! I ended up leaving it with a mix of TR6s and AL103s and I'll go later to the autoparts store to pick up a new set.

I just can't believe that the plugs literally started miss firing just by taking them off an putting them back on.
 


Hit one and mess up the gap?

Sure you didn't do...the noob trick..?

nah, I always do one at the time so I don't mess up the firing order. It's not missfiring now with the mix of TR6s and AL103s. I'll just put in a new set later. hopefully it wont do that again.
 


I installed brand new TR6s at .055 and it worked fine. I'll see if it's absolutely necessary to switch back to brand new AL103s when I get back to the 3.0 pulley. I really don't like how the car feels on the 103s. It has rougher idle with the VS cam and you need accelerate a little more for it to take off during normal driving conditions.

What happens if I run too hot spark plugs? KR or missfires?
 


LoL I scanned it on the way back home and the trims are now in the -12s and -15s. They were pretty close to 0 in cruise.
