Been battling a nasty misfire issue with my Bronco. it started shortly after I filled up at Sunoco. I immediately thought I got bad gas and flushed my system and cleaned my injectors. Since my fuel system was okay and I had no codes or vacuum leaks, the only possibility was ignition.
My super fancy scan tool software was not offering misfire data and I just assumed it was a function of the PCM rather than the software. I thought hooking up to an engine analyzer was my only option to gather ignition data. Anyway, I ended up dropping $40 to have a local guy plug in his fancy snap-on scanner. It immediately flagged #4 as misfire and once I swapped the plug wires the misfire moved to #3 so I knew it was a bad wire.
I am now better educated regarding the limitations of the scanner software I select and am looking at alternatives that support mode 6 among others.
I am 95% NovRun ready. Just have to install my new ram cylinder.
