Hi all,
I have a 1990 750iL stuck in the "limp home" mode. The check engine light is on. Here is my problem..
I have the Peake Research R5/fcx code tool. It gives me a reading of 0A for both DMEs. According to the manual, this code means Emission (Lambda) control.
Can someone please tell me what Emission (Lambda) control is. I am interested in knowing what part this is referring to. I have checked my air intake, the filter box, the Mass Air Sensor, and the boot exiting that. All are ok. I am at a total loss. Any help would be greatly appreciated.
Thanks!
Warren
