AGU running issues still.
« on: 27 July 2013, 18:56 »
I have a 99 T AGU and I'm still having running issues with it.

ive replaced the maf, coils, plugs, temp sensor, lambda sensor, all pipe work for silicone incase of any split pipes, cleaned the throttle body etc.

It was put on vag com and only faults were temp sensor and lambda sensor which have been done

It just won't accelerate properly, if you're nice and gentle with the throttle it's not to bad but try and give it some welly it just hesitates and jerks and jumps.

its been decatted, had a G60/ VR6 clutch, induction kit.

i have searched but I've tried nearly everything now and it's starting to bug the life out of me.

Any help and advice would be appreciated.
