I was changing out my spark plugs from the regular ac delcos to the ac delco rapid fires, when I got to spark plug #3 and noticed that it start spining when I tried ratcheting it out.... but it would go no where, it was loose too... My friend told me if I noticed any hesitation in it when ever I drove it, and I did notice a hesitation when ever I pull it out on the high way... Which was only twice so far. I barely ever drive cause I am waiting for my hypertech chip and hypertech 180 thermo.... Plus no tags no insurance. is disconnecting the drive shaft difficult cause I need to pull the tranny to replace the speedo sensor and the rear main seal.
The most important thing so far though is the spark plug, my friend came up with the idea of getting new heads.... I don't really want to do that but it might be best. Is there anyway I might be able to get it out and just retap the bore???

A Heli Coil usually works.....And much cheaper the new heads.

 

Sounds like the threads in the head are stripped. You could try helicoiling the head with the bad spark plug hole. Disconnecting the driveshaft shouldnt eb to difficult. Havnt had to unbolt the u-joints yet on mine but that shouldnt be too difficult. Whatever you do, just dont take the yoke out of the rear of the trans, itll be a mini niagra falls of ATF if you do.
