Need help figuring out problem w/ my celica Options

[Smitty2145]

Alright... I have been having problems with my car sputtering and stalling out on me for a few weeks now. This only happens after the car is brought up full running temp. When the engine is cold and i start it up.. it seems to run fine... I can drive it for a few miles... but then after i come to a stop sign and idle it has problems accelerating... it will start to sputter and sometimes it will stall out. most of the time it will start right back up... but sometimes i have to let the car sit for 5-10 mins before it will fire back up again.
Here is a list of the things that have been replaced withing the past 21 days

-Plugs
-plug wires
-dist. cap and rotor
-ECU
-thermostat
-a few of the vaccuum lines

I just ordered a new Vac. modulator and idle air control valve.... if anyone else has any suggestions please let me know... i love my car and it is really starting to piss me off that i can't drive it around reliably.
thnx

I already replaced the fuel filter and it didn't seem to make any difference. The fuel pump is only a year old... so it should be working fine. Is there any way for me to test if my tps is working... resistance test or something?

would help if that info about the pump had been in the first post, longshot but replace the fuel pump relay for ****s and giggles. a bad pump can burn the relay and cause problems later.
