Hey Guys

Just after some clarification. Am i right in says if i disconnect the MAF sensor whilst the engine is running and it does not stall then it is knackered?

I have just done that and the revs dropped right down but did not stall. Is it broke?

Cheers

mine either stalled or the revs went up and down erratically

So do you think i have to raid the wife's purse for a new sensor?

thats not exactly a true way of testing it.on your model car if u are in any doubt then i would replace it regardless,i was doing mine as routine maintanence procedure.if yours hasnt been replaced since new then defo replace as the results of a faulty maf could be NOT nice. dont forget to reset ecu after fitment.

for some reason i though the above test was correct but only for a warm engine.

Hi Mate I have the same issue , the info below is just what I have researched and read I am not telling anyone what to do as everyone has their way.

I have a flat spot around 3k and I have tryed a full service first , new ngk plat plugs leads , fuel filter etc etc.

But then i went on google and did a search on the issue , and it seems the way to tell if your maf has gone is get the car warm (dont trash it ) but make sure its warm then unplug the maf , if the engine cuts out its not the maf .

But if the revs drop then come back up and the engine continues to run it is the maf , a engine check light will appear on the dash aswell .

But As soon as you put the plug back on the maf it will go away .

I have ordered A new maf from my subaru dealer they are £94 plus vat for our year car and carry a 3 year subaru parts Warranty so worth a punt as mine has been on the car since new.

Hope that helps and makes sense ?.
