Hey Guys,

 

i recently got a manual twin turbo, there an issue where after hard accelaretion if i hold the clutch in to come to a stop it will cut out on me. it only happenes after hard acceleration.

 

i can stop it if i feather the accelerator but it is a bit annoying and sometimes quite dangerous!

 

Any reaon for this? i think it is a manual converstion too. Its got HKS twin dump valves if that has anything to do with it?

Does it cut out as soon as you press the clutch?

This is something that happens when dump valves arnt set up right, so it could that.

what have you done so far to diagnose it?

Boost leak is the most obvious to me, used to happen to mine like that many many moons ago and the recirc blanks were leaking.

Well its when i press the clutch in you can see the rev just drop beyond the minimum!

Idle control valve might need adjusting and check your tps voltage is stable.

I wonder if you need to raise the tick over a touch, what is at when fully warm ?

split clutch booster hose or leaking air in from booster servo can you hear air leaking under the pedals .
