Intermitten SES light....

Sometime the SES light is on when I start the car and it stays on the whole time I drive. Sometimes it never comes on.

When I floor it, it usually turns off. What is wrong?

I have previously gotten lean codes.

Yes, even though the light isnt on, the codes are stored in the PCM. Might be a dying sensor OR a tranny code. Those seem to do that to me. If its a dead sensor it will stay on. Either way it will be recorded in the pcm
