Today on my way to work I went to pass some cars on the interstate, and my SES light started flashing at me. According to the manual it means a engine misfire, and could result in catlitic damage. Truck when I was passing was pulling 5400rpm because she down shifted a couple of gears that I wasn't expecting. It only flashed like for 5 sec and then out, and hasn't done it since. The engine doesn't run bad or anything, and the only mod that I have done is add my glasspack. Is my truck in need of a tuneup? It has 32000mi on it. Any help would be awesome!!!!!
