ECU fault code 23
Hi, I have a 1995 UK Impreza turbo, with a full Miltec Sport exhaust system and K&N induction kit fitted. I recenty noticed an increase in fuel consumption so I reset the ECU and it then reported no faults. I have now driven the car for about 50 miles with the fuel consumption looking better but upon checking the ECU for any reported faults it is now showing a code 23 fault. Does anyone know what this fault code means please

Ok, is there an easy way to check a MAF sensor??, or anywhere around the Cambridge area that you recomend that could check the MAF for me. Would it simply be best to replace it rather than risk destroying an engine.

I have unplugged the MAF with the car running and the engine stopped straight away..... does this mean that the sensor is still ok and I should be looking somewhere else????

Doesn't mean nothing, had 2 MAF's go on me and the engine died as soon as it was unplugged but it was the MAF's that were gone.

I have now changed the MAF and reset the ECU, but I am still geting the fault code 23 
, could having an induction kit on cause the MAF to show a fault. Is it worth putting the standard air box back on or does anyone else have any ideas what I should be looking at????????????
