I have a problem where my car runs very rough on idle and cuts out after a few seconds. During driving its fine although slightly sluggish. When I unplug my mass airflow meter the car idles very smooth although it tends to idle high for a while before settling back down. While driving without the airflow meter it pulls well. I have swapped in two air flow meters from other cars and they don't make any difference to the problem. I'm now thinking that the problem could be something else or I have been very unlikely and now have 3 faulty airflow meters. Any help would be much appreciated. Cheers
