You could have several problems - one, for stalling, would be the accelerator module going bad. You could also have a failing Crankshaft Position Sensor (CPS). Replacement of both can be a DIY project.

When you changed your brake pads, you probably did not replace the brake wear sensor. That needs to be done. You cannot re-use them.
I did a spark plug and filter tune up at the dealer....it was expensive....but i have driven it about 90000 miles since then..i am gonna order the brake pad sensors online and how much is that acceleralor paddle?
