X15 2350 performance issues.

[Kiko]

So I think I figured the low performance issues. I blocked off injectors doing a leak test and found that injectors 6 and 3 were leaking. Have ordered some new ones. Thanks Rawze for your help.

I do have another question though. I still don’t have exhaust brake. With insite I monitored clutch switch, working, brake switch, working, exhaust brake switch, working, exhaust brake level, working, cruise control works, removed the valve cover and inspected. All appears normal, wiring is connected, solenoids test ok. When driving and I remove the throttle pedal while monitoring exhaust brake output circuit 2, 2, 3, and 4 and it shows inactive. I believe this is because the ecm is not telling it to come on correct?

Now one thing I did notice was that the throttle pedal on insite is showing 0 and 100 % when pushed but the multiplexed accelerator error limp home switch state is showing accelerator pressed. Can anyone tell me what this is or where. For giggles I plugged in j-pro to see any cab related issues and also saw that the engine desired throttle Valve position was 100 % when throttle is not pushed and throttle position was 100% at an idle. So I guess I’m wondering if this is related to this error limp home switch state and the exhaust brake not working
