why does my car keep stalling out when it warms up? It has a new fuel pump, new fuel filter, plugs, wires, alternator, o2 sensors, distributor cap and button, and new ignition coil. it runs fine when its cold but when it warms up it just stalls out! could it be the ECM

At this point suggest picking up a Haynes manual or perhaps your library something. The Autozone website may have repair info in the sites vehicle repair guide section.

Check the coolant temp sensor for the computer. A bad sensor can cause this problem. The sensor has two wires not one. The sensor can be tested with an ohm meter using warm/hot water to simulate coolant.

Check the EGR system. The EGR system is turned off when the engine is cold. Perhaps when engine is warm too much exhaust gas is allowed into the engine, stalling it. This system can be tested and parts bypassed to keep the system off when engine is hot for testing.

It sounds as if you are having an electrical problem..

If the car is giving you a check engine light, figure out what code it is.. it may tell you the exact problem.

its not giving any codes and the check engine light isnt on. when you give it a little throttle it runs alright but when you punch it to the floor it dies instantly. but once you put it in gear it starts to sputter and dies. if you get it to move forward it runs then stalls and come right back

A lot of components are not monitored by the check light system.

Check EGR operation and computer coolant temp sensor.

A bad MAP sensor can also cause this problem but it seldom fails. Check above items first.
