ahh i see you dont now !!!

scoobian

I'm surprised it still runs at 450rpm

have you changed anything?
has it always been at these revs?
when was it last serviced?

Brun

Maf is a possability. Try unplugging it while the car is idleing - if there is no change then i would swap that

I found out what it was ! The story goes like this lol. I called subaru they said it was my (carburetor)! was playing up and they charge £85ph. I then called my friend who said to bring the car down to him. I went to my friends garage and he pluged my car into the diagnostics equipment. Hummm no faults found, engine management light on !! errr that was me i took off the maf plug while engine was running and caused the light to come on lol He checked the idle speed it was between 700/723rpm. All other checks done all ok. Fault light reset all sorted. cheers for your replys
