Need Help With My 85 318i

ghead

My car is running real rich (so i was told) how can i fix this problem? Can it be fixed?

also i upgraded my front rotors to Brembo cross drilled and already had to have them turned once. the front right is making a squeaking noise. the rotors were not zinc coated and i replaced the pads with some auto store cheap brand. is it the rotors, pads or ? Thanks in advance.

You’ll have to find out why it’s over-fuelling it could be a few things:
1. Air flow meter baffle sticking
2. Temp sander faulty
3. Fuel pressure to high
4. Injectors leaking
5. ECU fault

Brake squeal is normally the pads not the discs try painting them with copper-grease where they fit into the pad carrier.

One other possibility with the rich running issue could be the O2 sensor. If it is faulty you will also probably experience surging, or eratic acceleration amongst other issues though, so take that into consideration.

Just a guess, hope it helps!
