This position on the directional just stopped working. I need to manually change the position for any lights to work at night. The daytime lights do not work anymore either.

My 2003 sequoia will start and then stop a few seconds later. But will start and run on the second try. Also it runs fine until I give it a lot of gas, then it's starts to buck. There are no vacuum leaks, I've changed the fuel filter and mass air flow sensor with no change. Any ideas?
