The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

My car started dying on me about every 20 to 25 minutes. Then I let it sit for 45 minutes and it starts up like it never had a problem and then does the same thing again. I thought maybe it was the igniter but I got a used one From the junk yard and it did no solve the problem.... any ideas?

Check Engine Light on
CEL from rear O2 sensor. Replaced sensor, canceled code, problem fixed. NOTE. almost any CEL on the 2000 300ES will be accompanied by a "traction control off" light. That is a design feature to protect the traction control system. One the 0-2 sensor is replaced and codes canceled, traction control light will go out as well.

the oxygen sensors had been replaced, but the #3 sensor had been replaced with a #2. Had to have #3 replaced with correct sensor.
