my Isuzu KB320 has lost Power , in the morning when you start it runs perfect as you start it after an Hour the engines starts perfects but fail to idle normally like starts misfiring and blow backs when you drive it doesn't go above 4000rpm and the engine starts consuming more fuel than normal, the engine might stabilize and runs perfect but will change at any point in time , there no Engine check light coming changed the Fuel pump and checked the fuel system everything seems normal changed the Airflow meter but nothing has changed

i would check coolant temp senor. if its reading are staying low engine will run fine tell warmed up. because pcm still thinks engine is cold and is dumping in way to much fuel.
Think of the coolant temp sensor as a choke

misfiring and backfiring a a common symotom to coolant temp sensor fault.
