The past couple of mornings, I've started the truck (stays parked in the driveway), and the check engine light will pop up after about 10 seconds of starting and running, but then goes out after about a minute.
I attached my SCT tuner to the OBD-II port (it also reads DTC's), it scans, but then reports there are no DTC's. I'm guessing my alternative would be to start the truck, as soon as the check engine light comes on, turn off the truck, then attach the tuner, and then just turn the key to on so that it can detect the code.
As stated, the code clears within about a minute after start. It just started doing this, and the only other thing I can possibly relate it to is that the past couple of weeks have had Florida with some cooler morning temps.
