2009 Impreza Rough Idle

Hi Guys ,
first time posting on anything like this but here goes !!!

So my standard 2009 Impreza will not idle properly and runs very rough on a cold start when i have a 1/4 of a tank of fuel ??? But when the tank is say half full or full to the top the car starts and runs perfect no problems no rough idle even when cold ???

Any advice would be much appreciated.

Location: Perth Australia.

How many Km's has the car done ?

Probably needs the in tank fuel filter changed. Usually changed around 60K miles /100K Km's

No harm in trying the vehicle has a lot of K’s about 210k . I just thought it was very strange how when it’s full it runs fine !!!
Have had this problem before ?
Thanks for the reply Don Clark
