Cool Running Problem

I just took the RV out for the first time in about three months. It started easily and idled great. Under mild acceleration still runs good, but under more acceleration you can feel it skip and not have good power.
Also I have a light on the dash that says brake that come on and alarms and then goes off again. Never know when this is going to happen, but it is not a constant problem.
This is a 2000 Newmar Dutch Star with a 8.3L Cummings diesel. Does anyone have any ideas.

No help on the question really, but could it have water in the fuel? I had that problem with the semi back years ago, but glad to hear you got it out...

The quickest and cheapest thing to do first is to change your fuel filters to see if that resolves your problem.

When you change them pour the fuel out in a container and watch for water or black slimy stuff. If you see black slimy stuff it will be algae.

It is CUMMINS, not CUMMINGS. No "G"in the name.

X-2 on the Cummins. It is amazing how many times your finger automatically goes to he "g" when typing this name.

I like the idea of changing the fuel filters too. While you're at it, you might also look into changing the dryer filter as well? If that's restricted, it might be causing your brake warning light/alarm issue?

Not familiar with yours but I suggest after your filter change to get a device that can read out the coding. I used to have a power problem and it ended up being a crankshaft sensor....easy fix. If it has been sitting for a long time you might try Power Service from Walmart. I use it quite frequently.
