My ESC has gone bad for the second time in the past few months. The first time we had to take it to as shop because we couldn't figure out what the problem was. They finally tracked it down to the ESC, replaced it, and it ran fine for about a month or two and now its acting up again. The way
I tested it (I saw it on another thread) was to disconnect the ESC and if it doesn't run any worse then it is bad, and that's what happened.

So I'm going to replace the ESC again but I'm wondering why it has happened twice now. Could it be related to the ECM? The mechanic told us if we had more problems that could be the source.
