compression test...

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.

Did you have the TB open...?

When checking comp, you need to have the TB open to get accurate (or as close as can be with conventional tester) reading from the engine...

That's something I never knew till about a year ago....
