Compression waveform shows some type of problem at arrows, sorry about phone picture. Any ideas what problem could be? Dead misfire at idle only, no misfires above 2000 rpm.
this momentary lapse in pressure change is represented by the anomaly in the exhaust ramp. Look for fault that hinder the operation of the exhaust valve (like carbon/sticky guide/valve seat issues)
Brandon's hindering the exhaust valve statement is good. My first thought would be a cam lobe or rocker arm roller issue.
Brin, What you’re saying could be true as well. Mine was more of a blanket statement. Cam lobe/lifter issue can cause the same hinderance 👍
Word! I agree with your statement. I was just taking a stab with the application in mind.
