[TR] Spark Plug Cap

[terryrs at comcast.net]

Second time it's happened over the past couple of years.  Driving from work in the TR3A, get a single cylinder misfire, runs rough, corrects itself shortly.  Pop the hood and it's easy to find.  One of the spark plug caps has come loose and makes a poor, sometimes not, connect.  Tighten them up and things are fine for quite a while.

I thought about lock-tite, but don't have faith in the electrical conductivity. 

Thoughts?
