Help with C0043 sensor.

ac stops blowing when i'm accelarating.

Changed oil and serviced transmission, now it is in high gear, but won't shift. The "M" shift indicator light does not come on when I put it in Manual, most of the time. It comes on periodically, and when it comes on, the transmission will shift. Error codes are P0796 and P0971.

It stalls at lights and cuts off alot, when I go up hills doesn't get much power, after the hills it goes pretty good. My van skips, wonder if it's my fuel regulator

we have had water dip out the rear doors as well. Our son is handicapped and the floor he parks his wheel chair on also has warped the plywood. Any ideas? Thanks
