Well if you car is able to make it past 60 mph, that usually a pretty good indication that you have compression ins both rotors.
You need a special compression tester from Mazda as well. This is probably the problem. It would register your compression in each of the 3 chambers of the engine. However, a standard comp tester will usually give you the highest compression of the 3 chambers so that's what's throwing me off.
