Toyota Echo - Misfire

It isn't much of a diagnostic.
Just having some fun making a video out of a very simple, basic diagnosis.
The real problem is water getting into the spark plug wells.

I like that handheld secondary ignition scope that you have!

my 2001 toyota echo had a bad upstream o2 sensor. it made my car misfire like crazy. i was able to isolate the misfiring problem to that o2 sensor by unplugging the wire harness to the o2 sensor. when unplugged, it drove perfect-- no misfiring. i didn't know a bad o2 sensor could make a car run so terrible! i will leave it unplugged until the new one i ordered arrives (permanently leaving it unplugged would permanently affect my MPG...) hope this helps someone else!

if you're having trouble with misfires, its pretty easy to unplug and see if the o2 sensor was causing the misfiring.
