And saw that when I pulled #4, the engine did not drop RPMs. All others did. I was going to run a compression check, but my tester will not work - the injector is too deep. Are there other testers that will work on a Z? And see, you know what you're doing - I don't. I have pretty much no idea what you're talking about right now. That's why I think it's probably in better hands with a mechanic than with me. I'm good at cleaning and driving my car, not very good at working on it. Just curious, what do you think would cause a cylinder to stop firing and cause the car to smoke (white)?
