Getting a stutter? Try this..

[Acecool]

I was driving around 145 to 160 in my car a few months back, and it started stuttering and I thought I blew my engine or something...

But, turns out the ENTIRE TIP of the sparkplug in cyl 3 was GONE.........

It kept giving spark and would only be a problem 1 or 2 times out of 10... Anyway, these were champion plugs, 5 months old.. I returned them and got NGK :-)
