That £290 price will be for the MAF sensor and the housing, you can get the sensor seperatly and its retail price is about £70.

Try giving Jim Childs @ Cheam Motors a call tomorrow on 020 8394 2263 he will sell you one via mail order if that is what you need.

See This Thread Rabout the price of Lambda Sensors.

Jods,

Same thing happened to me at the car's first MOT in June .

Quenbys replaced both the MAF & lambda sensors under warranty (MY99 car - less than a week of warranty left ).

Has your car been feeling a bit sluggish, more carbon than usual around the tailpipe, poor fuel consumption & irratic / higher than normal idle speed? If so could be the same thing.

Oright Huge. Exact Symptoms. Idle is dropping from 800 - 200 up and down like no-ones business. Loads of carbon deposits.
Difficult to comment on performance cos I've only just got it back after 2 months off the road. (been in a corsa )

Called Quembies and they advised MAF & lambda sensors replaced
"Best part of £600 please sir" say Quembies.
"Not so" says I with a LARGE sigh of relief that I purchased an extended warranty in May. Huzzah and Hurrah !!!!!

Due hopefully next week

Just done a bit of digging, and this should be the part number for the MAF on its own without the housing:-

22794AA010 (METER CP-AIR FLOW)

Don't beafraid of using Subaru Breakers. There are some very good quality ones around, and they will save you beaucoup money. GRADE A are my favorite, if they've got the part, it'll be in the post by the end of the day....

but, if you've got a warrenty....

I have the emisson report at home but from memory (not as good as it use to be )

Fast idle 0.3%, natural idle 0.5%, HC 200ppm and Lambda 0.97 to 1.03

mine were FI 0.06%, NI 0.05%, HC 0 ppm and 1.00 Lamdba thats with a catted DP, TSL straight thru centre and scoobysport BB. I heard fully decatted is very close to these limits and may just fail/pass.

Cheers

ChrisP
