Hey Guys,
I have this annoying check engine light that wont go away. The car keeps triggering a P2C77. I went ahead and installed a new o2 since it was also getting a heater issue as well, and all that did was clear the heater issues. The code says something about post cat signal, anyone ever have this problem? Plugs are NGKs gapped accordingly with roughly 5k on them. I would appreciate any help!
