Well after installing a new battery, plugs, cap/rotor, IAC, fuel filter, and air filter, the car still runs rough when cold for a bunch of seconds and sometimes stalls. Any ideas? TPS?

Could be a dirty IAC (idle air control). Its supposed to help richen the mixture when cold the way a choke used to on carbed engines.

Oops[img]smileys/smiley9.gif[/img] missed in the first post you said you did that. Umm.. fuel pressure regulator, coolant temp sensor, intake manifold gasket, tps, not sure what else would cause it.
