cant figure out what it is.... whole truck shakes at idle and when you accelerate at low RPM's it vibrates violently... like shaking change out of the center console, violent.... its the worst once the TC is locked.
ICP is 600-700 at idle and as high as 2700 accelerating.
DC is 12-13% at idle and never goes higher than 42%
fuel pressure is 68psi at idle and drops about 2psi at WOT in my daily tune and bout 10psi at WOT in my extreme tune.
ICP sensor has oil in it but unplugged it and nothing changed.
had the water in fuel light coming on under acceleration so i drained the bowl and nothing changed.... a month later i got pissed off with the light always coming on so I drained the bowl again and then pulled those fuel pressure numbers.... this time the light has gone away (bout 100 miles so far since i drained it) and it ran significantly better but its slowly returning to the old symptoms....
anybody have any ideas?
thanks
