The yellow engine light stays on since we have owned it. They say there is nothing wrong . If it doesn't give a code they cant fix it. We have had it in the shop several times since and all they do is clear the light and within 50 miles its back on. If the truck is off for 30 minutes or more the turbo works great. But after 3 minutes its gone and drops from 65 straight to 25 or 30 mph no matter the incline or with a empty trailer until you turn the truck off again. Do you have any idea on the issue?
