Need to help a friend
I let my buddy borrow my truck to haul his camper on weekend and he instantly became a diesel fan. So he found a 1999 sd on craigslist with 156000 on it and checked car fax to make sure miles were rightand he bought to truck and the story on the truck is that the power steering pump went out on it so they parked it next to a barn. well my buddy bought it and i thought. Long story short a RAT made a nice cozy home in the valley. It eat the IPR,EPR,and the sensor on the back of the fuel bowl. to no surprise it had a code for the IPR and EPR but it also has a code p1670. any help?
