Intake vaccum with wps500

Post by Jesper » Sun Jul 07, 2019 9:14 am

I am new to the WPS stuff, so thought that i would play around with it. It is A 2,0 natural aspirated engine, with very light/small misfire sympthoms 1800 rpm.
I messure intake vaccum,idle, and i think that it looks suspicius that every 2. drop looks different, like the valve overlap is different on 2 of the cylinders. Can anyone clear that out. I think mabay the tappets is worn out, because of a tapping noise cold.

Best Jesper
