1995 Cevy Lumina starts when cold after I turn it over a few times. And wants to stall on me. It Warms up and it runs alittle better but wants to stall and die on me. After it warms up it won't start till it sits and cools off. I give it gas it wants to die. I can hear it kinda back fire under the hood or like its choking some.

Hi Rick1959, Welcome to 2carpros and TY for the donation

Lets check the fuel pressure with a fuel pressure tester if its within specs if okay -clean out the idle air control valve and EGR valve and then test the throttle position and manifold absolute pressure sensors.

Also try this next time it refuses to start do below immediately don't wait for nothing this will give a basic idea about the fuel and spark

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard
