[TR] Stag missing a beat at speed but not at idle

[TERRY SMITH]

Hi SUjit,


My first thought would actually be wires, if they're carbon core.  Issues usually show up under load, as is your experience.  But you're going down the right path.  Curious how it turns out.


Best,

Terry Smith, '59 TR3A  TS 58667

New Hampshire and looking at 12 to 18 inches of snow tomorrow into Wednesday.

It eventually did start. On the way home I noticed the car missing a beat and ran rough at about 70 mph. I drove at about 60 mph but still notice the roughness.
