Can anyone help please, I'm at a loss.

Problem:

Once the Impreza has warmed up it seems to loose boost and only boosts at 0.6 bar making it alot slower. It runs amazingly when not quite warmed up in coldish weather, it even over boosts sometimes :-/ Not sure why its doing it, there must be a faulty sensor or something maybe. Has anyone ever had this? Remap maybe?

Its a 1993 import wrx FYI :-)

Thanks for any help.

Anyone?

 

i think 0.6 bar is when your car is running in "limp mode"...

Is the CEL on or anything?

 

Thanks for that :-) Yes, the cat light is on, but its only been on since I wired it up to a UK spec lamda sensor... it had the same problem B4 the tho...???

Thanks for the pointer mate. If anyone else can back that up or suggest anything else it would be more than appreciated.

Cheers,

Nath
