a4 1.9 tdi misfire and power loss
 

Hi im new to this forum so please bare with me.
Im in urgent need of some help. I recently bought an a4 tdi (ajm). It has a misfire on cyl 2
And has hardly any power. After about 3000 rpm it feels like the car is just revving but not accelerating and once the revs are up high it is hesitating badly.
I have changed the injector wiring loom with no result.
Your help and advice will be greatly appreciated
Thanks
Andy
