My STi 3 (1997) won't pass it's MoT as the CO emissions are nearly 8% on the fast idle. I have put the Subaru diagnostic equipment on it and the airflow sensor reading indicates it needs replacing. I have already replaced the lambda sensor.

I am told that a new airflow sensor is £290 + VAT. Does anybody know where I can get a secondhand one from or the part number for a new one? I'm also wary of fitting one from a different model year. I'm planning to go away on Friday so need a solution quick.

Helppppppppppppppppppp!

 

Try Grade A Subaru for a 2nd hand part

 

Let us know how much they want for 1...
