I too doubt they even got the new filter installed with the seal from the old filter still in place. I tried that before, didn't work.

tried to hook it up on efi live and see what was goin on... didn't show nothing outta the ordinary, confused the guy how it was running and put a fuel filter on and it took care of the problem. it caused all kinds of engine codes and headache over a 30 dollar filter.

thanks for the help.
