We spent 11 hours on a 2014 ProStar with a stuck injector cup, and just when we got it free, the customer rolled in with a second truck that had the same exact noise, has anyone else had a run where the same failure shows up twice in one day?
I used to figure those back to back calls were just bad luck, like the truck gods messing with you. Then we had a day with two blown turbos on the same make and model within an hour and it hit me, that's usually a bad batch of parts or something in the fleet causing it. Now when it happens I start asking what those trucks have in common instead of just cussing.
