H&S issue or else?

[CATDiezel]

Hey guys,

Have an interesting issue. The dash boost gauge reads maxed out and the minimax reads 15psi at idle.

This issue just started and man will it roll the coal when it's like that. Also my exhaust back pressure will barely register if at all unless I floor it. Then it will jump up.

Anyone have any thoughts. I'm too hungry to think about it and driving through the Ozark mountains ye only thing to eat is road kill.

I've restarted the truck several times with no change. Also with key on engine off no change.

Help

Thanks.

Map sensor?

I'm not a pro at this but the same thing happened to me. I unplugged my map sensor and then plugged it back in and it worked. Worth a try

Thanks. I'll give it a try. Man this thing will poor the coal. Embarrassing. And that's in NO POWER setting

Well. That seems to have fixed the issue. I'll check it tonight when I go to church. See if it remains fixed.

Odd.

Thanks for the quick and accurate response fellas
