think the choke is controlled by your ecu,through various sensors on your engine and may need a code reader to determine your problem but would check for air leaks/split hoses in your air intake system,worth a look,good luck.

i had driven the car already then had it parked for about 30mins before starting again and it cut out at low revs so isnt doing it just when the engine is cold, it dosnt have ht leads its electronic where is the choke system and how do i check this and thanks

Does it cut out at low revs, or just cuts out.
Next thing in line to try would be HT leads, But check you fuel system first. try running at slightly higher revs after starting. If it runs, then when warmed up a bit drop back, if it keeps running the the choke system is faulty
