Okay, here is everything:
-2013 Chevy Equinox LS, 4 cylinder
-Problem started in spring (did not have the money to fix it, single dad with 4 kids so its been tight)
-Exhaust solenoid changed
-I changed the air pump, and just checked it and its connecting hoses to make sure I did it right
-Both check valves changed
-Runners (not sure what they are exactly) cleaned and a lot of carbon there
-Check valves removed, inspected, cleaned and no issues found
-Current code: P2440, permanent
I've read that code is for a stuck valve at bank 1 or bank 2. Myself, and more importantly my mechanics, are stumped. I only did the air pump myself because it seemed to be the simplest thing that I could do, everything else is over my head.
Thank you for whatever ideas you have! I'm just trying to get this fixed and pass inspection.
