i'm having the exact same problem.
car drove fine forever, minor issues here and there. then last week, i can't hold an idle at all. engine will stall if i try to hold it at under 2k rpm. i'm revving along local streets, growling my engine at 2k at redlights lol. i cant toe-heel very well, so i just stall let the car stall for turns, and just bump it back to life. the power steering cutting off just as i start the turn is a bit scary though. anyhoo, i've concluded its the AFM. now i don't know how to fix it though... do i just replace it? also, someone told me it could just be poor grounding. i've tried to search the forums about that, and got a few faqs. could someone please clarify what exactly i should do for grounding? i'm a car noob, and reading: 'there's a nut under the exhuast' means little to me. what exactly do i do? something about 8gauge wire, to my battery's neg terminal? please, if you have some spare time, guide me a little more explicitly as to what i should be doing when it comes to grounding. thanks for any help. '90 s5. btw. |

I had a slightly different problem; my car was fine one night and drove awesome. I parked it and the only thing that was different the next day was that the temperature dropped 30 degrees. At about 3000RPM it bogged and had no power... I checked vacuum lines and found no leaks, I checked AFM resistance and it was good, checked timing and TPS they were ok. Re-checked all the turbo related lines and they were all ok except the turbo inlet duct had a good size crack on the turbo side, I wasn’t convinced that something before the turbo was causing power loss like I was experiencing so I took the UIM off and put a fresh gasket in between. Problem went away.... I must have had a leak inbetween the UIM and LIM. I later patched my TID... I couldn’t figure out why it was good when I parked it and the next morning it was shiat...
