[Mk2] [Turbo] idle and stalling

[sketchmyster]

got a mk2 rev2 turbo and had a problem checked for codes and came up with code 52 which ive changed the knock sensor however the car now stalls after hard acceleration. no codes sowing

Are you hitting fuel cut?
What PSI is it hitting?

[sketchmyster]

nope not hitting fuel cut as only running standard boost at mo but has been running and raced at 1.2 bar with no problems

So it's stalling when you are coming to a stop after accelarating? Do you have a vent to atmosphere blow off valve fitted?

yer a friend has said release it abit so have but havnt tried it yer

[dobbar]

Mine did the exact same thing, was thinking BOV was on it's way out whereas in fact it was simply down to a dirty ISCV !

[Peter Gidden]

Sounds like usual Rev1/2 problem.

Either ISCV is not operating correctly, or a cheap rubbish ebay dump valve or branded better dump valve is leaking.

If ISCV is OK, refit the OEM dump valve.
