Code 42,44 car is misfiring and when you rev it the let off and try to rev again it won’t... just bogs and hesitates like crazy. Car doesn’t seem to rev higher than 3500 rpm

And fuel pressure is 42 when key on. Idle is 38 and when rpm goes up fuel pressure is 36-42 area moves around a bit
timing is set at 6 degrees .

Thank you it ended up being my ecm !
