GWM engine cuts when slowing down

[SHOUSEHAM]

Hi, is there anyone that can help me. i have a GWM H5 2.4 2012 petrol engine SUV that is giving me issues. The engine started cutting when I am slowing down. So when i step on the brake and clutch the revs drop to 0 and the engine cuts. I have tried waiting for the engine to warm up but same thing happens it starts off good and then dies the further I drive and cut more often when I stop at traffic lights or if I need to gear down to 1st. I got an error light on my dashboard which when checked was "P0107: manifold absolute pressure/barometric pressure Circuit low input"
when we checked it, it said that there was a MAP sensor error but I went and replaced it and cleared the error this past weekend but the engine is still cutting and we also found that if I am idling and I put on the aircon it also cuts the engine.

Sounds like something a dirty ICV or MAF could cause, get a spray and give both a good clean, might as well do the whole throttle body.

Could be a bad fuel pump. Most ECU's don't have any sensors on the fuel pump, so low fuel pressure or any fuel pump issues won't be directly diagnosed, and will cause other codes to trip.
