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.
