I know I’ve taken a little flack for my MicroTech computer…but on the plus side it did tell me a couple of months ago that I had a “bad Crank Sensor”.  Of course, it turned out to be a bad connector - the Mazda factory pig tail coming out of the sensor had a bad connection in the plug.  It must have been intermittent because the engine still ran fine for the most part – just a little rough every now and again.
