Misfire #7 again, again, and again...
#12
OK I have to ask a question. What is the purpose of a oscilloscope? I have used volt-meters, noid lights compression gauges etc to diagnose misfires but never even heard to use an o-scope. I read a little about it but don't completely understand it for use on an engine. Seems like it would only work with sophisticated electronics. Do you use it just to see if the coil is putting out the same current/spark pattern as the other coils?
From my experience it's probably an intermittent wiring short, possbly even a faulty ecu. Both of which are fairly common with ford and dodge vehicles.

The analog ones are much more accurate than the digital but good luck finding one.

It must have been the hand of god that made it go away but it has. IDK how. I'm going to do the compression test this weekend. The wife doesn't want me touching it till then, just in case she gets more bad news and I tell her she can't drive it till I replace another expensive part, lol.

my sugestion...i had some screwy connectors on my car. Wiggle all the wires on the injectors and the cops, i had 3 bad ones that inadvertanly would cut out whatever it was attached to, just wiggle and tug. Altho it caused short term problems then went away completly shortly after...musta created a better connection lol.
