I have a 2002 Chevy s10 v6 vortech engine that's starts and sounds good but when it's reved to 1500 rpm it bogs down in park. when I teyed to drive it around the block it bogged way down and wouldn't hardly go I replaced the spark plugs, 2 O2 sensor, mass air flow sensor, and throttle position sensor still nothing. When I ran for codes it came back random misfire, both O2 sensors and mass airflow sensor

I'm not sure I don't have a way to test it at the moment but I also just replaced the fuel pump and replaced the pvc valve if that could help narrow it down?

You need to read the fuel pressure. That should have been done BEFORE replacing a fuel pump.

Yes, you should. We need to know the exact pressure.

I also need the exact code numbers being set.
