This post may belong at the end of b2boggs thread but I thought it may be seen faster here. My '07 was also cranking alot before starting and idling rough It would seem to be fine at speeds above idle but I suspect the mileage may be affected.(according to the on board system)I haven't actually "done the math" yet.
The local Dodge dealer's Sprinter tech had me bring it in for a scan but nothing turned up. They suspected some questionable fuel at one point but that doesn't seem to be it. BTW, I changed the oil(full syn)and filter along with the fuel filter and air filter before taking it to them. The problem was there prior to my doing this.
They then suspected the Mass Air Flow sensor. When unplugged after starting the engine, the idle will smooth right out. Plug it back in and the rough idle comes back. Made sense to me. After replacing the sensor it didn't change a thing. Same rough idle. So far though, the engine has been starting right up without excessive cranking since the day after I delivered it to them. Maybe there was a fuel issue after all but that would be quite a coincidence.
At any rate, they are in the process of checking with a tech from a different dealersship that they've used before. If anyone has any ideas I'd appreciate them sharing. When(if) these guys get this figured out I'll post the result. Maybe it'll help someone else. Have a great day everybody and stay safe...................
P.S. Turtle, if you read this, would you be up for a couple of PM's regarding batteries and converters and such?
