Isx 2350 485hp. Surges has no power

[LLT]

Hey sorry I don’t know what happened but I did write a reply it just didn’t appeared.
Anyway
Yeah, first with the high pressure switch. Is it the one by the compressor? how many ohms does it suppose to have or how should a check it?

And yes I want to de-mandate it, I did imagined MM would not work for this engine and I didn’t want to just take anyone’s advice, but I trust Mr Rawze.

I will pm mommaburt hope he can help.

Thank you guys


Oh! I did work today and the truck runs fine, I guess it was the exhaust pressure sensor or the one by the EGR. They are the same part number. One had a lot of restriction but I didn’t pay attention to witch one.
