Mustang GT Question: Random Power Loss at Highway Speeds

[kntr]

I figured mine out too... so far My NEW fuel pump was bad. This is the second time Ive had a NEW part that was bad.

Wellll...the stupid thing did it again! Grrrrr! New fuel pressure regulator is going in soon. I'm thinking the transition to WOT and open loop may be hanging up the regulator....maybe a bit of trash in it.

Any easy way to change the regulator? Stupid bolts are upside down and looks like I'll have to remove the upper intake!

Kanter...at least you got yours working!!!

So far...
