Exhaust Pulses | Using exhaust pulses to identify a misfire.

Описание к видео Exhaust Pulses | Using exhaust pulses to identify a misfire.

A long time ago I asked for help in a forum about using tailpipe pressure for diagnostic purposes. I was told tailpipe pressure for misfire diagnosis is worthless these days being we have misfire monitors. He was wrong! I've personally seen other technicians/mechanics criticize others just because they themselves do not have information or knowledge on the subject. That's pretty sad...

I ended up doing my own research, watching videos and having some fun experimenting just to learn more on the subject. Using tailpipe pressure to identify a misfire will only take about 5 minutes!

This vehicle turned out to have a faulty ignition coil. The pressure sensor used was the WPS 500.
