Hello and welcome,
I'd try new spark plugs and check all the leads to spark plugs, but I'm sure there'll be plenty more suggestion so wait to see what concensus of others is first.
Does it run ok when warmed up??

Is it only when it's cold you have problems or does it run rough when warm? Also is the engine fault light on?

It sounds to me like it could be the coolant temp sensor(it's a different signal to the dash temp sensor so that may still work), it could be telling the ecu the engine is already warm so it's running to lean when cold.

hi , there are no lights on dash not even engine managment light. yes once it gets to running temp it runs fine.

Coolant temperature sender is the next thing I would change then.

i would check that there is a cold start valve fixed to the car there is a product fix to this isue were the car nedds 3 or 4 cranks to fire when cold if this valve isnt fited or is fited and not working then this will cause the problems u are facing
