Hello and Merry Christmas to all. I believe I was able to log some files of my truck ECU. A strange condition showed up with the engine at closed throttle. The MAP sensor voltage spiked. Can anyone make sense of this? Thanks for you help.

foulty sensor or harness is mostly reason for that
best regards
Thanks for the reply. Actually the condition shown is when the engine stalled. I looked at engine speed and the rpm,s were zero. This is one of the problems that I am chasing. It acts like I'm running out of fuel, but pressure is rock solid. I drove around with a gauge in the cab and there is no movement. I even turned the pressure up, but this did not change a thing. I checked all the usually suspects, pump fuel filter OPS and the entire circuit. As soon as I learn how to log correctly I will be able Identify or eliminate possible causes. Thanks again.
