I recently bought this 1986 325es with a bad water pump, i'm coming from DSMs so I'm mechanically capable. I did the water pump, timing belt, new hoses, belts blah blah. So I fired it up and it drove fine until it started to get warm, a little over half. It then brought up the "check" light flashing in single intervals and would run like absolute crap. It won't run about 2.5k rpms and if I give it gas it will bog down and die.
I looked online and found that the single flashing light means its an air flow sensor malfunction so I went to the junkyard and found a near perfect looking one and bought that to switch it out. To my misfortune it still ran the same and threw the same single flashing light.
What else can I try to replace/check? I'm extremely new to these cars but i'm use to tearing apart my 91 gsx, on e85 , apart and I just don't know where to start.
Any ideas are welcomed!
