surging? or what...

[MtPaul401]

This has happened 2 times in the past week, I'm going slow with a little accelleration, probably 20-25 mph and the engine surges like I'm pushing on the accelerator, tap/surge tap/surge tap/surge.
Ever go over a bumpy road and your foot sort of bounces the pedal and you get that surge? That's what this is like, but I'm pretty sure I'm not tapping on it.
Odd.
Any ideas?

BUMP!

I noticed the same thing on my 99.5 7.3L it's just as I'm resting my foot on the peddle cruising behind someone... very slight, my first guess is a TPS type sensor but hopefully someone smart knows more

It's only happened once in the past week since I changed the fuel flter. That was pretty gunked up after only 8000 miles. I'm hoping that's all it was. I'll keep you posted.

What's the TPS sensor?

Throttle position sensor

Oh. A couple of questions about that then...
where's that located?
Can it be tested to see if it's good?
Is it expensive to replace?
Thanks!

TPS's are pretty reliable, it's basically a reostat but they can get a worn spot in places where they are used alot for example at rest on the peddle at cruising speed. Which is why I kinda expected something along those lines, but these fords are drive by wire which is why I posted your thread up hoping someone might have seen this before.

Oh, drive by wire, sort of like my 94 GMC gasser. Still, wonder if there's a way to test the TPS?
