right where do i start lol 93 uk auto tt 88,000 standard no mods

 

1. Car has a low knocking noice on start up with the sound of tapits aswell or and by the looks the vvti spring are on the way out

 

2. Car stalls when coming to a stop under braking if the engine is about to die and i come off the brake it saves itself, and if you are on full lock and blip the throttle when the revs come back down to idle it cuts out or sometimes saves itself but it struggles

 

3. When flooring the car from stand still it goes well but when crusing and i plant it sometimes it doesnt change down, this is only when its in 2nd or 3rd gear doesnt go to 1st. also i get a goose honk noice when it changes gear at 6900rpm i think it is (when giving it death)

 

4. when coming off the throttle when driving the engine jumps, its like dipping the clutch when driving a manuel and bring it up when got your foot on the throttle, box doesnt seem to be releasing.

 

5. under full boost with the window down i can hear an air leak or is this normal?

 

any help on solving these problems is a great help, ive done a service on the car due another oil change soon, cleaned and blanced throttle bodies, checked air leaks by spraying brake cleaner on every joint, cleaned the top pipe on the idle air valve and car has been set up on conzult, and no faults found

 

thanks again regards andy

recirculating valves?

you must have good ears! try a pressure leak check, but dont overpressurise as some of the system is designed for vacuum.
