Idleing and startup problem
 

have a 97 TEG turbo, setup:
B18b motor
t04e turbo
DSM 450cc injectors
Tuned at 6 psi with Uberdata
here is the problem, when ever i start the car in the morning the idle is around 2300 rpms, it seems to take 10 min for it to drop down to normal, while it is droping down the idle is really bad, it goes up and down, up and down, when i was getting the car tuned my tuner said it was because of the DSM injectors,

another problem is when the motor is hot from driving and i let the car sit for a half hour, i go and try to start it and it wont start, or sometimes it will start and then die right away, does anyone have the same problem, or know what the problem is, THANKS
