I just bought an 05 2500 and it seems to run fine and gets good mileage. But when shutting off, has a slight bit of run-on. Anyone have any thoughts on the cause and a fix?
It may take a secound or twofor the ecm to shutdown when you turn the key off. You might wanna try changing out the ecm relay under the hood as it could have sticking contacts.
