OK here's the deal.

For some time now, intermittently, the F-150 5.4 Triton will sputter. The road speed is always about 45 and the RPM is right at 1200. It's like it's not getting spark for just a moment and then we're back to normal.

I wonder if the throttle position sensor is the culprit.

It'd be nice if that were the problem since it's only about $60 and right up there on top where I can reach it.

Heard a rumor the TPS is built permanently into the throttle body and you have to swap the whole thing. Any truth to that??
