6.0 eng, When first started for the day, it runs very rough and wants to die if I don’t give it a little throttle until it warms up. Then it works fine for the rest of the day (even if it sits for several hours). Check eng. Light blinks for a minute or two then goes out. FYI…Could not get my OBD tester to give me any codes. (Changed batteries but that did not help.) Tester didn’t say “no codes” it just kept resetting to “turn ign. On and push test”. Any ideas what I need to check for the cold rough idle problem?
