plugs just had this problem regapped to .7 all fixed

[sinistaGTR]

get new plugs and gap to .7

[MBS206]

The rule used to be.

Get new plugs and gap to 0.8

I'm starting to think how some other people are.

Stuff doing close plug gaps. Go buy some new coils. That's the true issue. Regapping plugs is just hiding your issue.
