In cylinder pressure transducing revisited
Posted to Technical Theory Forum on 8/6/2010 28 Replies

This vehicle is a 99 Ranger with a 3.0L. I am dabbling with in clyinder pressure transducing. I have saved known good wave forms not enough but I am working on it. I have one in my bay right now with an issue. Has a misfire, has audible vavle train noise, and on accell it pops back through intake. I have narrowed it down to cylinder #2. So I hooked up my fluke PV350 and Snap On Vantage pro and this is what I see while running [1999 Ford Ranger XLT, Engine/Propulsion Waveform] here is a video of it as well [1999 Ford Ranger XLT, Engine/Propulsion Waveform]

IMO it looks like I have no vavle movement at all.

I have other waveforms from another vehicle that is fixed I want to use this thread for discussion as well. I know some of this is in the archives, I have researched them as well.
