I had similiar issue trying to figure it out now. Check engine light blinked at me never stayed on and blinked at me again never stayed on though. Scanned it today has codes p0101 , p0113 , p0300 , p1111. Looking for input have no idea where to go from here.

 

I am still trying. I checked and changed some deteriorate vacuum tubes as I read in diagnosis literature a few said to check vacuum seems liked it helped. In my case I also changed air temp sensor downstream from mass airflow in the intake tube. It was less then $20. Woth the gamble I think... I am taking truck today to a guy who does inspections etc. for co. I work for. Supposed to be taking 3hr trip thursday afternoon. Need to know if its ok to take truck or not. Truck can not be down....

I would not drive a vehicle with a flashing SES light. It indicates a malfunction that can cause engine damage.
