Yeah, I realized that after. It's hard to follow since there's like 3 different people w/ problems going around this thread. Edit, just dumped my old post since it was irrelevant.

Stalling is usually the result of a bad cat. It's restriction on the exhaust causes it to back up into the engine and chokes it out.
