Hi, I own a subaru impreza uk2000.

I've been having trouble with idling issues, after upgrading turbo.
As soon as I upgraded turbo it went in for a remap. By this time idling was not right, it was going to about 400-800 rmp. Whilst having a remap, got advised to possibly change lambda sensor. Nothing happened.
Carried on driving the car and idling got worse to 200-800 rmp, and if i put my foot down, then put my foot on the clutch, it may cut out.. not always but sometimes.
So done more research and it lead to MAF sensor. Changed that and the idling was fixed, but now I can't put my foot down.. The car judders.. no power is coming out.
Any help would be great Thanks!

 

Will have been mapped for a the bad maf, need ot take it back and get the map sorted.

Why didn't the mapper sort the maf for you there nad then?

 

Ah makes sense!
Mapper believed it was the lambda sensor, he didn't think it would be a problem..

 

really?

christ, get a new mapper

 

Mapper is well known, from here, I'll see if he can sort me out
Thanks though!
