Unhappy HELP! Car not going past 4000rpm...




This morning when i drove to work, i noticed that when i tried to accelerate past 4000rpm, the car refused to acelerate and let off afew bigh jerks...

Just went out agian, and it did the same thing. I have also tried with the "Boost Off" setting on the AVCR...


Feels like this is happning asoon as the boost trires to come on or the turbo tries to kick in...

Nothing has changed, the car was driving fine yesterday evening.

Any thoughts?

Just got back in...

The car seems to drive fine if the accelerater is pressed gently...but when full throttle it jerks..

After afew tries it seemed to fix it self...


Also seems that on gear change example: changing at 7000rpm from 2nd to 3rd, the revs drop to just over 4000rpm, and there feels to be a loss of power for a second befoer the car takes off again?? (as if its loosing preasure)

Maybe related..

Anythoughts....Anyone....
