Undergapped/Non Matching Gap. What happens?
Well I just realized that last year when I did my plugs I didn't gap them, the people at the parts store told me that they were pre gapped and to not worry about it. THIS time I found out differently. the TR55s are NOT gapped at .060, they're usually gapped anywhere between .048 and .053 is what i found. So, for the past year, my car has been running on plugs gapped at the previously mentioned gaps, not matching, not to spec. So what exactly can happen from not gapping properly? I am now having a starting problem, so I'm doing the plugs today GAPPED PROPERLY to see if that solves it.
So yeah, whats the deal? and what can non matching gaps do?!

Odd...all the NGK'* I have ever bought had the sleeve over the end to ensure the .060 didn't get bumped in transit.
Overall... I wouldn't worry..gap them properly and move on.

Well I can say that I think that was my starting problem, because it hasn't happened since. Although it might have been that I let the computer reset, but also the plugs are all now evenly gapped and it also has a new o2. It definitely was not idling as smooth as it is now. Response is quicker, it feels much more peppy, starts faster, and idles a little slower and smoother.
