Tonight (after driving the car for about a total of 30 minutes) I stopped and shut off the car then got back in and when I started it (normal start) and began moving...I noticed that it was idling higher (roughly at a 1000-1100 rather than 700-800). Then about 1/2 way home the engine started surging between 1800rpm and 2500 rpm. I stopped the car in the driveway and ran it up smoothly in neutral in different RPM levels and could not repeat problem. After opening the door and getting out I noticed that there was a large rich gas smell to the air. Is this probably a vacuum problem (as it was in my E32) or could it be one of the Mass air flow meters (please say no).
Not sure where to start with this one.
Thanks for any advice.
Brian
