The little 1.6-liter engine in the NA6 Miata moves too much. This engine movement, combined with soft factory differential bushings, contributes to a lot of drivetrain movement.
The now ST6 Miata has had some serious electrical gremlins from day one. Intermittent starting issues, random fuel cuts, and erratic idling to name a few. I knew at some point I would rewire the car completely. What I didn’t anticipate however, is that I would give the rewire a first pass just days before the regional championship at Nashville Superspeedway.
