2003 Tahoe 5.3. Been getting this code for a while but only when the rpm’s hit 2200 and it’s random. Seems to be more when I sustain above that rpm. Changed fuel filter, new AC Delco plugs, wires and just last week all the ignition coils. Did nothing. I’m attaching the FIXD code reader output for you experts. What do I check next or is there someone out there that could diagnose it for me?
