Monitoring the LOAD goauge with my scangauge II on my 2005 sprinter (with 72k miles), it seems to quickly go to 99 under what seems to be minimal pedal pressure. It seems to have good acceleration though it doesn’t feel like the turbo is kicking in like it used to. My mpg has been steady (around 20). While cruising at 60 it seems that the slightest hill or pedal pressure will send the gauge to 99. Plus, starting from a stop, with a light foot, it jumps to 99 easily. I clean the air cleaner regularly but that doesn’t seem to make a difference. Is there anything I should look at or am I just being overly concerned about nothing?
