Hi all

This is my first post (which obviously means my car has a fault)

Intermitant hesitation whether hot or cold - most noticeable after being driven hard (UK car)

Connected it to two OBD code readers - both list misfires from all cylinders -
The car has been regularly seviced and had a few parts replaced-

The Bosch FSA 560 code reader tech info suggested MAF faulty -
replaced with new Bosch unit - fault still present (breathers, intake and oil separator cleaned also)

Plugs were changed twice recently using dealer parts - no change

Coils replaced in desperation - fault still present


Visually leads look ok though they are the next cheapest option to replace

Thanks in advance

 

Fixed it myself - though thanks for reading

After changing Air Mass Sensor I only cleaned as far as the top of the throttle butterfly/valve

However removed Throttle body today and cleaned with electrical cleaning spray

Fixed
