Have you checked the throttle pots on your transmitter? Possible it's a problem with the transmitter rather than the esc, and it's just co-incidence its happened with the change of esc.
I've personally had this issue before, where for some reason I had a bad throttle potentiometer, and cause the throttle range to vary. Made the throttle feel very very weird.
The other thing... Check the motors tabs for any possible short (same on the esc). Just a small bridge could cause an issue.
EDIT - going on the above, check the sensor port on the esc... Quite possible it's not engaging properly as some have said.
