I have a 2004 v6 4motion bora. It has 107k on clock and I have recently had the car serviced replacing all the coilpacks and an injector clean. My problem is that car is displaying some weird behaviour.

Many times if I use full throttle it feels like some rips the handbrake on. The motor revs cleanly but slowly. On partial throttle, more power no issue. I have had it on the computer via a VAGCOM and nothing.

Wondering whether anyone has experienced the same or has any suggestions?
