CHECK ENGINE LIGHT IS ON

2004 Isuzu Axiom • 6 cylinder 2WD Automatic • 99 miles

My 04 axiom is throwing 2 codes. P0172 and 1239. I have changed plugs, o2 sensors in the exhaust and fuel filter. Still hesitates with reduced speed light on

P0172 = Fuel trim too rich

P1239 = High fuel pressure system.

You need to check the fuel pressure regulator operations.
