My MAF seems to be on the brink, If it is plugged in, the engine has low power and bobs around when accelarating. If I unplug it all the power return and it runs fine. Any idea how much these cost to replace and if it will be a problem leaving out for the time being.

I can do you one for £10 posted if your interested

They're about £85 new from Ford. No, it won't damage anything in the interim.

same thing has happened to mine, if pIugged in the car has a IittIe party befoe acceIerating.
