Saturn Repair Problems? Ask a Mechanic for Answers ASAP
Hi Im david, cleaning the throttlebody and mass airflow sensor is a good idea, also cleaning the idle air control motor and egr valve is a good idea. its a fault off the bank 2 sensor 1 circuitry , so replacing more than that one was not necessary. if cleaning the above mentioned components does not help then we will have to look at the wiring from the sensors connector to the ecm.
