Symptoms to watch for

  • See a related documented issue (cold-start rattle), a related documented issue (misfire/coolant-in-oil), a related documented issue (whistling/rough idle/lean codes), and a related documented issue (harsh shifts/limp mode) for the shared-platform items' own symptoms

What To Check
