My 96 F-250 7.3 check engine light comes on every time I start it and stays on for about 1-2 minutes. Engine seems to run fine during this period. When the light goes out the engine either speeds up greatly and dies or sputters and then runs fines until it needs to be started again. If I attempt to drive with the light on the transmission shifts very hard. I find no codes in memory when I check. Do you have any ideas as to what or where my problem may be coming from?
