Hi dave ,thanks for replying car not showing any fault codes 1.6 diesel 95ps ford recon it could be injectors 

My fob key didnt work on my 2008 petrol Ford focus .it wasn’t the battery I used normal spare key to open doors and lock it on drivers side . It’s only got the key hole on that side . Then the lock jammed and can’t lock car at all so had to leave it open in case it self locked like it does sometimes ! And leave car window open to put arm in in case It locked itself . I called a man that renews  fib keys who I got my key from last year . He talked me through what  To do and it worked fob . Turn key on with normal key not fob one to ignition  but not start car up! 8 times till I heard beep keep doing it .then press fob after you here beep 

Check all the easy stuff first

When was the fuel filter last changed?

 

January this year cleaned the airflow sensor in October and there was a way better performance with car then went back to normal.put new airflow sensor when the filter was changed and that only made a small difference,cleaned and put back original sensor and performance is back but for how long I don't know

Has the issue only appeared since changing the fuel filter?

No dave have this car for over 10 years got it with 50,000kms on it was never great power wise rough idle now has 140,000kms ad I said in post when the sensor was first cleaned that's when I noticed the difference 

OK check injectors
