Hi Everyone,
I have a 2020 kw t680 with 184k miles with the following codes. truck will derate.
1142-Injector solenoid driver cylinder 3
1656- Engine misfire cylinder 3
5897-engine misfire cylinder 3
it is currently in the shop for 6 days and they can't diagnose the issue just yet. Any idea what I can do? thinking of taking it to another shop.
