I have an int. hesitation while accel at hiway speeds, maybe once a week. I hooked up a fuel pressure gauge to rail, and hooked up a scan tool and I get a 10 psi difference in readings between the actual pressure at the rail and the electronic reading at the fuel rail pressure sensor. Just wondering if anyone has any experience with this setup? Thanks, Bobby

It uses a mechanical returnless fuel system I believe. I have the 02 with the 3L ohv too. I'm having the same issues. My fuel pressure measures low according to the shop manual and in spec according to the Ford emmisions control diagnostic manual. If you find out anything please let me know as I've been chasing this problem for some time now.
