2000 Ford F150 V8 Four Wheel Drive Automatic 175000 miles
My f150 4.6l auto started flashing the theft light and would not start. Disconnected the battery and reconnected it and it started fine. Now it seems that while driving upon any thing other than light acceleration it shakes and seems to shift in and out of gear. The motor winds out but the trans seems to kick in and out. Usaually this is followed by the truck stalling. The gauges at times will go crazy for a slit second or the theft light will start flashing. Have hooked it up to a scanner and all it shows is water temp sensor and and engine head temp sensot however nothing is overheating. Drove it 700miles on a trip the other day got back home and it started again? Took it to a ford cert mechanic and he scratched his head. Anyone have any ideas?
