Hey lads iv had the following fault codes and looking for your help to narrow it down, car is 02 vrs with only mod being a Forge dv006,

Codes are as follows

P1136 (maf, vaf sensor low input) this was after maf was changed so maybe still in the system??

P0102 (long term fuel trim idling bank 1 system too lean)

P1297 ( turbo charger pressure loss)

Anyone shed any light on this? Car seems down on power and hunts slightly on idle.

Any help greatly appreciated

Checked all your breather hoses? They can cause all sorts of problems.

How does it run with the maf disconnected? If it runs better than the maf is at fault, non genuine ones are unreliable

When disconnected I get the same warning as the asr being switched off and drives the same really.

Clean the throttle body first! Reset the codes and see what happens then!

Will do that tomorrow thanks

hunting at idle is most likely a vac leak on the intake side
