About once a year, my 8.1L would go in to "limp" mode, which is reduced power. My gauges would not rear right, etc. I would shut the engine down and go out and using the chassis battery disconnect switch, I would switch power off to the engine. This seemed to reboot the engine electronic control module and I would be good to go for maybe another year(10,000-15,000 miles) or so.
This is not a new trick as mechanics have been disconnecting the battery to reset the electronics on vehicles for years.
Sure it would be nice to find out what caused the issue but I was more interested in continuing my trip. If the problem came back immediately after I reset the ECM, naturally I would have done more to diagnose the problem. Since it only did this once a year or so, I figured it was caused by some sort of blip in the electronic controls and NOT a bad component.
