bump bump.

 

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.

 

YES JUST REPLACE IT WITH ONE THAT HAS THE SAME CODE ON IT AS YOURS

 

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...

 

its my afm, thre a friends on and she cranked right up and idles mooth at 800 like always, got mine coming from mazdatrix, but while she's down i plan on doing a bit more to it.

 

aaand nevermind, she stopped idling again... and now wont crank, just spins and spins...

 

shane trammell thinks it could be my tps, sound possible?

 

check it for codes?
