snap on ford cylinder contribution test

does anybody else have issues with this test? I was working on a 2002 town car it had a misfire I could feel it. shows no misfire on the test. so then and there im not that impressed with it. get the autel ds708 out power balance shows cylinder 2 misfiring. it ended up being a bad terminal on on the injector connector. fixed it and all good after

Oh yeah, I have problems with it all the time. Had a really wild trip with an F-150 last week that was showing me misfires on all cylinders, engine was totally smooth...

I'll glance at it sometimes, but usually ignore it anymore.

do you know where to report issues at with there scanners? the reps don't seem to care.

I don't even bother trying that function anymore.
I froze my old Solus trying to graph it on a V8 ford once, and I've never gleaned any trustworthy reliable information from it unless there was a dead miss.

ha makes 2 other people saying the same thing. do you guys scope intermittent misfires or use another scanner??

Most of the time i can find what I'm looking for in mode $6, t.i.d. $53.

I'll scope the primary on suspect coils on a test drive, can never get the paddle to sit in one place.

Or, I'll follow Mode 6 and just start testing spark and pulling the plug. It's a gamble, yeah, but a reasonably safe one

Havent tried the Autel on one yet, should experiment with that...
