Greetings,
I have a 2012 Volvo Vnm with the d13 and a 10 speed Eaton. I have been having a rough idle problem with it for the last 6 months. The mechanics have replaced a lot, the turbo, egr cooler, dpf, turbo actuator, exhaust manifold. I’m tired of them just throwing parts at the truck. When I start the truck and it’s cold, the truck’s idle will go up and down it’s a 6 second interval.
