Yesterday i was pullen a long steep hill unloaded and then my my engine cut out  and "Service Engine Soon" light came on. The truck would Not rev over 2grand and my speedo seem to move up to about 10mph when the tach was lowering rpms in park. I shut it off and wasnt happy for about ten mins or so.I fired it up and it reved out fine BUT the "service Engine Soon" light was still on. I drive about 12miles or so and stoped and shut er down. I fired it back up and there was no light on !! I was on my way home cuz of the 4th and drove at least 80 mor miles after the light was off and still nothing!
