Hi guys. Back with another problem. From some time now, my car had some problems on high revs, at almost 6000 rpm there was an hesitation in the acceleration, but after i go trough that spot, there was ok.
I started with the spark plugs, coil pack, the lambda sensor, injectors. Now, i got an Op-Com interface on the car and i found out the car was running lean at 6000 rpm. Untill those revs, the car is going on rich. Also, if i go easy with the throttle, the car goes until limitation at 7200 rpm @0.3 boost, if i kick down at 0.8 bar the car goes suddently lean.
I checked untill now what i wrotte up and i was thinking of:
-inverted fuel filter, with the bad direction of flow
-bad fuel pump.
Is there anything else i should think of?
Thanks for any help guys, cheers.
