I have a 95 regal that idles rough and stalls when the car warms up. Before it stalls it makes a backfiring sound, it shakes, then it stalls. After it stalls the car wont start for hours. Can anyone help me out?

When it stalls don't wait for hours do below immediately to catch it if its fuel or spark problem.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -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,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
