try the champion eon2 plugs there around £20 from motorworld
and are a much better plug to use
you will find the plugs you have are just standard champion plugs with a GM stamp on them
and a high price tag to boot
also i would remove the coil pack you have and check the 4 plug holders
as the springs inside the 4 holders need to connect with the spark plug
and it is common for the springs or one spring to go out of position making a bad connection
BAD CONNECTION SPRING HAS MOVED OUT OF POSITION
CORRECT SPRING FACING DOWN
