Truck runs fine unless I punch it. At 20 MPH the RPMs increases to 4 speedometer goes to 55 and stalls. At 55 MPH and I punch it transmission shifts to 3rd gear RPMs go to 3 speedometer stalls at 65-70 with pedal to the floor. No check engine light but my scan tool which is a blue driver has a fault of po068. The first 2 images are from today. I removed the negative and cleared the system. The remaining images were from driving for several days.

Hello, I'm Danny.

If there is a fault with truck and it is not fixed just simply removing the battery cable to clear codes they will return after driving 25-50 miles and will show up again. I've attached diagnostic suggestions relating to code P0068. This code is for the MAP manifold absolute pressure, MAF mass air flow and will cause the symptoms you are experiencing. Let us know what you find. Hope this helps and thanks for using 2CarPros.
