an update
The car started up as is with trouble. When stepping on the gas, the car struggled. Burning rich because of smell.
Then.........
we've taken the O2 sensor out. It had white stuff on it. We bought a new O2 sensor and reset the ECU. Car started up great! will wait for next CEL if it comes up again.
Other than that, CEL is gone for now.
Thanks for the pic Jon [in CT]
