In this instance ... The check engine light came on before the smoke clouds appeared at subsequent start ups. So.... The P2187 stored at that time, the beginning of the AOS failure. That was the "lean at idle" event. Its possible that the plugs I removed being "lean looking" was the motor trying to compensate for the extra oil in the system..... I cleared the code and drove the car. It felt perfect. Plugged in the test tool this morning and have a green light and no codes posted.
Thanks .......bob
