1999 Spider erratic idling
I have just aquired an Alfa Spider 2liter twin spark. I totally love the car, but the improper idling is driving me up the wall.
The morning after I collected the car, she would not idle at all after starting (she started first time). I nursed her with the throttle and then drove her on the highwah 40km to the office. At the first traffic light after getting off the motorway, she idled at 2000 rpm. At the next traffic light, the engine was "hunting", in other words rising and falling continuously between 1500 and 2500 rpm. At the third light, she was idling normally at 1000rpm. The 4th light she was all over the place again, and so it continuous every day. Any ideas?
