Effects from NGK loose plug tips???
Yesterday, I sprayed at the track and it surged on the big end for the first time in years, but ran great N/A afterwards. A/F averaged 12.0 the whole nitrous pass, so being rich wasn't an issue.
Today, I pulled the ngk plugs and two were finger loose. I've tightened them with some pliers prior to installing them, but a few have worked themselves loose again. This is not the first time this has happened. Just wondering if the loose plug tips could be the culprit.
This is becoming a pita.. I may just go with some Autolite AR472s and ditch the NGK brand completely.
I don't know what plug you guys use, but my plug has 2 models.
1 has a solid tip & one has screw on.
Everything else is the same, but for whatever reason, they make both styles??
