I have had this problem for over a year now, and I also have heard that the transmission "Reverse" and "Drive" switch (or sensor) can send bad codes and cause this effect...I will one day research this and find the absolute source of the problem.

In the meantime, I had replaced the OVP some time ago to cure a hot start problem, but the surging still rule out the OVP
