Hi Alinux,
The MAF replacement helped greatly with the problem. The MAF wasnt working properly. Although as you can see from other posts, there are other things which can cuase idling issues.
ANY leaks in the air pipes before and after the throttle body will cause the the idling to be out. I have found that it needs a complete seal on all connections.
If you have had your throttle body cleaned, then check the seal which sits at the end of the big air pipe, as it connects to the throttle body. This seal is incredibly tight, and when it's put back it can bend, so although it looks from the outside as if the air pipe is connected properly, the seal could have an air gap. This happned to mine, and by replacing the MAF, getting the throttle body cleaned, and makingsure that this seal sits correctly, ALL my idling problems were cured.
Dont forget the Lambda sensor can also affect performance, and idling, but the MOT should show whether it's working ok, or not, so you can rule it out fairly easily.
Have you done a diagnostic? if so are there any trouble codes?
hope it helps
Mike
