Engine runs like a lean gasser.
Good morning everyone. This has been going on for a while now and I keep putting it off but its the time to figure it out.
here is what AE told me;
KOEO - p0475, p0605
KOER - p0476, p0541
Contribution test - p0269, p0284
buzz test came back clear and all sounded good
Chang rotational velocity - 1).2-1.4 2).9-3.3 3)2.1-5.4 8)4.1-6.6
Is there anything else I should check or watch?
If all you smarter people could please point me in a direction that would be great. Thank you for your time.

# P0475 - EPR - Exhaust pressure control valve malfunction - Open/grounded ckt., solenoid open/shorted, failed PCM
# P0476 Exhaust Pressure Control Valve Maffunction
# P0476 Exhaust Pressure Control Valve Performance
# P0605 Internal Control Module ROM Error
# PO541 Manifold Intake Air Heater
# P0269 Cylinder 3 Contribution/Balance Fault
# P0284 Cylinder 8 Contribution/Balance Fault
When i had the last two the new international CPS cured it(269.284). Not sure on the 605.. I got that once before also. But went away also when i canged the CPS.. On the exhaust, I would clean the exhaust back pressure sensor and tube. Not to experienced with codes but here is a bump.
