Joe Rappa Made it to level 2!  Looks like you are on your way to becoming famous

There are some folks that are VERY accomplished when it comes to analyzing vacuum waveforms from the intake and pressure waveforms from the exhaust. If it's a mechanical problem with the engine(and you're looking for sticking valves), you can certainly see waveform changes if you do those measurements. I've got a friend that swears by the Sen X First Look.
