Testing methods for Light Misfires

F@ck the lack of OE manifold vacuum ports . You could Drill or melt some holes in dem plastic fantastic intake runners as close to the intake ports as possible and thread in some Yamazuki screws with orings or adapters with rubber caps and hook up a Motorcycle Manometer -Carb synchronize r setup.

I'm not sure whether it is time for you to stop taking your meds, or get back on them!
Either way, you're due for a change.

Question; does the First Look system have a quick and easy way to measure both the air entering the engine (via air in the intake duct, OR, the vacuum) and the exhaust out at the same time, and then graph the two well on a scope screen-??

Crusty,
The SenX tool is just a pressure/vacuum probe that's sensitive to small pressure changes. It makes a nice, clean signal while doing it. I imagine you could add MAF or MAP to make the signal more useful.

Vacuum tranducer

You could experiment with a vacuum transducer in the intake or maybe while your going a leak down you use a vacuum transducer in the intake or breather to monitor the leak. The best part is you have access to known and an good engines.knock yourself or and keep us in the loop
