The engine light turned on repeatedly following a 'reset' by my mechanic. He suggested using higher-grade gasoline with lower ethanol content, which seems to have done the trick over the past 2,000 miles or so.
I have had everything changed from the Oxygen sensors to the fuel pump and the light will not go off. I think it might be my gas cap as I noticed cracks around the seal. I guess I will have to wait and see.

New cats and sensors didn't help when the engine light threw a code for catalytic converters. Toyota wants $2800 for their cats, and had no advice when I emailed them. Putting on a simulator now in order to pass smog, RIDICULOUS!
