Hello Okay so you’ve checked for vacuum leaks and replaced the map sensor on the intake manifold? You failed to mention what has been done to the motor and what management you’re running. I suggest a piggy back or stand-alone management with a dyno tune at a professional tuning shop. And see if that won’t sort things out. Once had a similar problem and it turned out the management I was running at the time needed a separate unit just to make the car idle. From what I understand from your description it sounds just like what I had. The backfires indicates too lean conditions and I would recommend the car be dyno tuned. Even get an AFR gauge with the heated lambda in the exhaust and you can monitor exactly what the fuelling condition is when the car gives the trouble. Also perhaps did you have a look at your fuel pressure regulator for sufficient pressure at idle vacuum?

have you plugged it into diagnostics to remove all faults as well as doing all what MrRocket12 has said
