I leave just five minutes away from work, and just from work to home my recently new number 3 spark plug blows out of it's casing. Poofs of air now come out of its place?
Do you
have the same problem?

When the car was bought that was done after the first time the plug blow out. I forgot to mention this was the 2nd time this has happened. The port less then 8 months old?

You will have to get a helicoil inserted, this is a new stainless steel thread insert, the head should really come off to to this as it requires re drilling the plug hole over size and re tapping for the insert.

If you have already done a helicoil and it is still blowing out, I feel that the hole is to big now and the head will have to be replaced.

No I don't, first you say that the spark plug blows out you say it has been helicoiled and it still blows out now it's a fuel problem. What is the actual issue here?

I would look for vacuum leaks at the cylinder and have that injector removed and tested.

Your using platium plugs right. Replace the wire and plug. Nothing in compression will cause this.
