running rich problem
Hello everyone, I have an obd1 95 m3. I recently just put an s52 low milage engine in that i got for a good deal. I also did the obd1 swap for it so it would work for my car, I kept the original obd1 ecu. The problem that im having is that my spark plugs seem to only last me two weeks before they turn black from running too rich. I am currently using the s52 pink top injectors with it, could that be the problem that I am not using the original green ones for this ecu? I also just replace the CTS, and the IAT sensor to see if that would help the problem, but it did no help anything. I will try to get you guys a picture of what my plugs look like as soon as i get a chance. If anyone has any ideas please let me know thank you.
