spark plug won't stay tight
OK guys, this one is really stumping the heck out of me here. A while back I did a tune up on my truck (00 Blazer ZR2 4.3L) including plugs, wires, cap and rotor. Now a couple weeks ago I noticed the truck hesitating in the 1-2 shift. Trans was rebuilt (twice) very recently, so I can't say that's the problem.
I looked into it and the spark plug all the way in the front of the motor (closest to the radiator) on the drivers side was loose. As in, 3 or 4 threads from falling out.
I took it out and inspected it, all the threads looked fine so I double checked the gap and reinstalled it. Truck ran fine again for a few weeks, and now the other day it started hesitating again. And yet again, that plug was loose.
What in the world could cause this and how do I stop it from happening? Any ideas?

is it possible your using the wrong plugs ? sometimes plugs can be knocked out if there the wrong ones
Ive seen this happen before
if the plugs are a little longer then suppose to be they would come out slowly

this is just weird. Id change out the plug,maybe the threads are eff'd from the factory..
or better yet,switch a plug from the cylinder beside it..
I HOPE your threads in the head isnt bad...god that would suck.......
