Start by checking DTC codes https://www.hdforums.com/forum/softa...des-dtc-s.html

If my check engine light stays on a second or two after start... Does that mean something without needing a fancy doohickie to check codes? I could swear it's a light check when you first start, but every once in awhile it sticks around a few ticks.

CHECK ENGINE LAMP
When the lamp turns off after being illuminated for the first four-second period, it will:
a. remain off if there are no fault conditions or trouble codes currently detected by the Ignition Control Module.
b. come back on for an 8-second period if only historic codes exist.
c. come back on, and remain on, if a current trouble code exists.
