04 4.7 randomly dies.

[Steve Mizar]

I have a 04 4x4 with the automatic transmission, the problem I'm having is it will stall randomly, when it does the code it throws is 2074, I had it in a shop and they could not figure out the problem, there aren't any vacuum leaks, I have replaced every sensor on the engine including the PCU and I had the IPM rebuilt, sometimes the idle will fluctuate and sometimes the transmission wont down shift when coming to a stop, Im at a complete loss, any help would be great...

I wish I still had the video to show you. However I bought a cheaper aftermarket throttle position sensor from a local auto parts store. It did not work well with my truck and I had the same troubles. As I was replacing it with an OEM sensor the bad one came apart into several pieces. If you haven’t tried it I would make sure the TPS is an OEM one.

Could be time to change the fuel pump

It was the aftermarket TPS, I replaced it with an OEM unit and it runs great
