I guess I'll have the dealer run a diagnostic when I get my inspection done. But my question is, if I bring it to the dealer when it happens to not be on, will they be able to read the memory of errors? Or does the CEL light have to be on to diagnose the issue?
Aftre $700 at the dealer, mine ended up being a fuel sensor and an oxygen sensor.
