2003 7.3l f350 superduty.
when i start the vehicle in the morning and its 30Degrees or less i will less it run for 2-5 minutes and then move out, the truck starts easy enough, runs quite well, but the SES light will come on briefly as you head down the road. as i'm slowly accelerating it will com on and stay on unless i take my foot off the pedal. also if i floor the pedal it will go out.when the truck is at normal operating temp the SES light never comes on. i did notice last summer when towing a 12k lb trailer it would come on under strain of a hill. any suggestions?
