Re: chaning a MAF Sensor
I'm pretty sure that the car will not idle correctly, but should perform at higher revs.
The normal problem with a MAF comes at higher revs (failing to rev over 5000 rpm, etc), so by disconnecting and trying again, you can eliminate or pinpoint the MAF.
If you do try and clean the MAF take care as the "hot-wire" is glass and easy to break. Use an electronics spray from somewhere like Maplins that doesn't leave a residue and let it dry completely before you connect it back up.
An old air filter will let more dust/dirt through and this can cover the MAF... mine was black when I first tried this as there was a small gap in the intake pipe where it joins the air filter box, letting unfitered air through. Then again, it didn't look like the air-filter had been changed in years .... which it hadn't!
