Intermittently my check engine light comes on and the eco indicator no longer comes on; when this happens starting the truck turns into a PITA to the point that I wonder if it is going to start at all but by the 2nd startup it is gone....until next time. It is not a solid problem which is why my mechanic hasn't been able to diagnose/fix he thinks it's the ECO system locking a cylinder(s) open or closed. Anyone have this issue and a fix for it?
