Car stalls at idle and pressing accelerator pedal just makes it misfire.

Hello, an engine misfire and engine stalling may be two different things, or could be related. Engine performance testing is needed. There could be more when one fault occurring, so - it's important to take things step by step and check each area to figure out what is missing -- fuel, spark, air, emissions control, timing and so forth.
