Analyzing Cylinder Pressure Waveforms, Part 2

In Part 2 of this Maximizing Tools series, we continue our discussion of alternative approaches to diagnosing an engine using the pressure waveforms from an in-cylinder pressure transducer. In this article we analyze the Valve Timing and Ignition Timing tabs on the waveforms.

Pulling Codes: A Mercedes-Benz Story – A P0300 Analysis Using Exhaust Waveforms

This article will document the P0300 code for a 1996 Mercedes-Benz. A single cylinder misfire has occurred, and the technician decides to clear the code in my presence. I advised that it is a good strategy to maintain the code information for review. It’s clear that misfire activity can be challenging on some ignition systems, and I’ve found through my research that all of the car manufacturers appear to run their monitors in a similar fashion, but it’s still wise to review their service information for the differences and details of their systems.
