Hey guys, reckon you could help me out, I'm having some super frustrating issues with my b4, its engine cutting if i use more than quarter/third throttle at any rpm, even sometimes before boost kicks in so I'm thinking it's not over boosting. 

 

Here's a video i recorded today to show ya 

 

basically what happens is the engine cuts instantly and engine breaks until i ease off the pedal, then right back into full acceleration because it holds boost while engine breaking. Either that or it jerks uncontrollably until i clutch save it. The cars very dangerous to drive in this condition and it's put me at risk while overtaking before . engine cut seems to happen way easier the higher the car is in gear.

 

While i had the black plug under the dash connected to read my ODB codes i took the car for a drive and there was only one engine cut in second gear in like 10 mins of driving with a lot of full throttle, so now I'm really confused.   

 

if it helps this is the vac line setup I'm using:   1cc1a3ed.jpg   157.3KB   9 downloads

 

Here are the error codes I've got

 

P1237

P1239

P1235

P0031

P1249

P0249

P0250

P1247

 

and its not the fuel pumps fault, I just installed a walbro 255, reset the ecu, still same codes as above.

Help would be greatly appreciated, i just want my suby to drive properly for once :'(

Cheers 

 

 

Hey guys I'm new to this forum, anyway I have a 2001 b4 twin turbo which makes no boost until 5000rpm. I've had 3 error codes come up as following:
P0031 (HO2S heated oxygen sensor Low)
P0250 (Turbo wastegate solenoid B Low)
P1199 (DPS)
So I have the car in at the local STI shop (STechnic) and they rkn I need a new DPS, which they can't source. I've searched everywhere for the part and no luck. So do u rkn u guys could lead me in the right direction for this bugger of a part or even have a DPS you're willing to sell to me, either would be much appreciated.
Cheers
