2003 international dt466 .no power uphill any idea?

[@ryanb6658]

I’m trying to figure out why mine won’t go over 25 not running right

[@alberthernandez1223]

Mine does that to trying to figure out why it doesn’t got power empty or loaded down it has to be flat to get it moving really slowly

[@pingling123456789]

One possibility is restricted exhaust due to partially clogged muffler/catalytic converter.

[@williamquick6153]

Electrical issue. Icp is way way too low and its reading engine oil temp at 139,000 degrees. Check wiring to sensors i bet they have bad wires, terminals or oil in sensors

[@josephhendricks6533]

Its your icp pressure. It drops when you throttle it. To a pressure it wouldn't run on. Replace the sensor

[@zm5189]

Isp sensor replaced already.
Maybe I need to buy another one.
How much psi should be when throttling?

[@danielapastor8963]

Is it an oem one?
