Right carryin on from my thread :

I kinda need some advice as i dont now what im lookin at...Basically i have no boost at all and when it does deside to work it will work till 3.1krpm then just cuts out..
Ive done all the check for boost leaks and there all fine...Im gettin really poor fuel consumion around 40miles to a 10er without boost as it aint working...

Anyway Djscorch(adam) done me a log and scan before this is what came up..

All i know is that i need a new lambda sensor but no idea which one..Also a CTS as im still on the orginal tbh..
I have disconnected the battery a few weeks ago and unplugged the maf last night to rule it out..
And i do have a open induction on aswell..

This is the log i did this afternoon and i only went to 4krpm as it wasnt goin anymore as there was no pull/boost what so ever..

i have no idea if my wastegate is broken..

is my maf defo dead?
Also what about the cts and lambda?

Just need a list of thing i need to replace..

Edit: Mork i did unplug my maf last night and then took it for a run...So that is what the error is as it stored it..

so can the CTS and lambda goes my car not to boost if there both knackered..

And which lambda is it i need ? front of cat ect?

Aright...

As i have no boost what so ever in any gear...Drive like **** tbh...And my fuel consumption is really bad...Ive been quoted 65quid each for the lambda but i need to now which one and were it is...

i disconnected the battery the other week to clear the codes so that is what that code is and the maf one is when i unplugged it to test it and rule it out so that that code..

the others have come back but i dont have no dash light (EML) at all..

And the car just wont boost ...It sometimes will then cut out well before its begans to spool up

aright...Must be different to my old vauxhall then..

but yeah the 18010 - Power Supply Terminal 30: Voltage too Low
P1602 - 35-10 - - - Intermittent
16486 - Mass Air Flow Sensor (G70): Signal too Low
P0102 - 35-10 - - - Intermittent

is me disconnecting the battery and the other unpluggin the maf...

So that leaves 4 to be explained?

yeah the maf is when i unplugged it 2 night ago and then went for a drive to see if it ran anybetter?

So the CTS & Lambda are causing my poor fuel consumption..

Now would the N75 cause my boost issue as im still on the orginal one..

im gonna do...

new Cts
new lambda
ECS n75 / or standard one..

also were about is them lambda sensor

cheers big lad..

gonna buy cts and n75 now then lambda later 2morro..

is this the cts i need
