Default Re: running rich, shuddering, bucking, surging 2.9

sorry to bump an old thread but have you checked your fuel pressure regulator? i was getting round 11mpg on my 2.9l and that went up to around 19 after i replaced that. there should be a vacuum line going from it to the upper intake mine had fuel coming out of that line so thats a quick thing you could check.
