Hi, I am new to in-cylinder pressure waveform plus this Autel scope is a mess. However, something about this capture doesn't make sense. I got a misfire on cylinder 4. Am i looking at a valve sealing problem? Any input would be great
What transducer are you using? I assume this is engine cranking its wide open throttle since we don't see an intake vacuum event (which is not ideal for much more than peak compression) ideally engine idling and snap throttle is where you will see issues. Lastly making a tool profile for the transducer to see psi rather than voltage will help to tell what is excessive leaking vs normal amounts but may bot be needed if the cylinder has major issues
