New LS1 Owners - Newbie Tech - Always do you own work...

Changed my plugs this weekend (car in sig w/ 29k miles).
I hardly every drive this car but have been noticing a slight miss for some time now. Plugs were installed by my 'old tuner' some time ago and here's what I found:bomb: #3 plug was really loose w/blow by and every plug had a different gap from .040 to .060.
Installed TR55's gapped at .050 and now runs smooth as silk.

Just an FYI:burn:

Nice! good job! make sure you get some anti-seize on those threads

I did. He didn't, had to wrench them all the way out.:mad:
I also put dielectric grease for ease of boot removal next time.

how long ago were they installed?
