I need some help regarding the latest issue.......Ever since the head-gasket has been replaced, the car idles like an automatic bus when stopping. For example, when I'm coming to a stop, I'll press the clutch and brake pedals, but the car will idle at about 1500rpm (compared to before when it would idle at +-850rpm when the clutch was pressed). Then when I do come to a complete stop, it will still idle at about 1500rpm for about a second or 2 before dropping down to the normal +-850rpm. Sometimes when I am stopped (traffic or waiting for someone), the revs will increase from the normal +-850rpm to 1500rpm then fall back down.
Could this be caused by the Idle Control Valve? Will cleaning it cure this "automatic bus" syndrome? Will the mass air flow meter also cause this? And could it also be caused the timing? I presume these were taken out and put back in again when the HG was changed.
Also, does anyone know where to buy ashtray bulbs from? I've managed to take the rear one out, but I can't seem to separate the bulb from the holder Is it all in one and only can purchase it from BMW? Or is there some secret James Bond 007 Austin Powers way of separating the bulb?
*Extra info: e36 1998 saloon/sedan, so 1.6 litre M43 engine. The car starts with no problems.
