the .1uF helps to get a little more stable reading, but not solves the problem. I´m worried about the project is going to be installed on a car, with (a think) a lot of more noise...

Tks.

The "A" series parts are much more sensitive to noise & power spikes than the non A series. Be sure to place a 0.1uF capacitor between Vcc & GND with the cap located as close as possible to the PIC.
