Wondering if there are any specialists willing to take a look at my 02 impreza wrx as it seems to be having a problem with hesitation higher up in the rev range.
The turbo does spool up to about 4000rpm but then just seems to hesitate the rest of the way through the revs. There is no CEL light on either.

I have been reading various posts from guys on here and SIDC stating it could be a MAF or Lambda sensor problem but would like someone to take a look at it?

Any suggestions folks?

 

you could try japerformance in ellon they are ok in what they do or wallace performance in brigde of don not sure of the numbers like but am sure they would have a look at it for u!

 

Or you could always ask in here

[that will more than likely be the A/F/R Mate
They are really bad in the newage impreza's

 

Not too sure what you mean by the A/F/R manifold mate, can you explain to me what you mean?

Cheers

 

I think he might be meaning the air/fuel ratio.
