Mx5 turbo won't catch idle when warm and stalls
 

Hi everyone, I'm new to the tuning scene and have just finished my 2004 MK2.5 turbo supplied by Malian (definitely would NOT recommend, 90% of parts were missing or wrong) I had it running perfectly on jack stands for about 30 mins then after I've reversed it off the drive to configure with auto tune it's not holding idle properly. When it's actually moving and I let off the throttle it drops down very low, sometimes manages to pull itself back but usually stalls then aswell.

Running very rich atm, almost as if choke isn't disengaging when warm. Once it cools down again it seems to run fine again. Checked the spark plugs and they're a bit sooty but dry. Really not sure what's going on.
