is that unter the carpet in the back??? that would make it MUCH MUCH MUCH easier to do what i need to do.. i was able to get my exhaust out of the way and the straps down for the tank. i didn't want to touch the rear end..

that milky lookin stuff was most likely water. that would explain some things. could be sugar but ive never seen what sugar does when mixed with gas. pull the fuel filter again and dump it out in a glass jar and see whats there.

im surprised it didnt have something on the map or maf sence we unhooked them. egr would make it run rough. no fishing tomorrow so ill see if i can make time to come over and we can see what the fuel pressure is doin, check to see if the injectors are firing. check this out and see if it helps.
