I Keep on getting my Check engine light come one whem i go down the motorway.
Had a select monitior tell me the 02 Lambda sensor was up the swanny.
Fitted a new sensor,reset the ecu and its still happening.
Idle C/O is 9%
eek:
Took the car to a Bosch tuning agent near where i live,they had the car for the day and said there was a signal fault from the lambda........The fault is i imagine the MAF sensor.
We are getting a car in next week so we can swap the units round.
Is there anyway of checking the MAF on a 1996 STi 2
Cheers

I think Darren means 02 = oxygen as opposed to O2 = 2002 Model Year.
The "classic shape" does not have the 2nd Lambda sensor that the MY01+ WRX has that detects a "failure" of the cat in the downpipe. I don't know whether the MY02 STi has the same arrangement.

Had the 02 sensor changed on mine and the problem has just re-occured. The dealer now says it's the airflow volume sensor (MAF)? that's faulty now, going in Wednesday for the work.

i ve got an sti v 5 type r, when it was on idle the revs used to fluctuate from 500-1000. when i checked the co, it was 9%, but the check engine light didnt come on.
so i took the MAF sensor of a mates car and fitted it on my car and the problem was gone, the revs droped down to 750 where they should be.
cheers mate
