PROGRESS Both sensors have to be trashed. Continuity on all afm wires tested just fine from the ECU to the harness at the AFM. I reset the ECU, and I reset the S-AFC. Started the car with NO AFM, and idle is perfectly sitting on 14.7 no bumps, misses, or sputters. Narrowing it down straight...

I don't think they went over 200hz, maybe 100 when I rev.

There is one small difference between the 89 afm and 87 sensor. If you look under the "pillar" that the sensor stands in, you'll see a small hole at the bottom of the 87 sensor. No clue what it's for though.

I've tried that too. I just did a resistance test with both sensors. 1.62 (on the original sensor) 1.69 (on the second spare sensor) Which should be about right. :( *I suppose I should pull a lot of electrical tape and shielding away from the main harness and inspect it all for damage.*

I said the same thing. A good deal came across for a VPC, but I decided if I was going to get anything it would be the maft-pro. This sucks though, I can't do anything till I get my paws on a multimeter.

They go up.

10:1 idle... then if you slightly press the throttle, it goes to 19:1. This sure is a fun one. I think I've narrowed it down to the sensors I have. One sensor idles like complete crap, and the other seems to idle a lot better but still not the way it should. Next in order will be a confirmed...

I didn't mean to say "before" it. Will I still get continuity from the ECU if I have the S-AFC wired into the main harness?

Keep the pulley if you want to, it doesn't effect anyone else. However I'd worry about what JP said about the harmonic balancer.

Accelerate heavily in 5th gear up hill, and see if the clutch holds.

You'll need more boost for 300's.

It'll weaken the actuator spring... but by that point you'll want something else anyway.

Wire is soldered now. Idle is still extremely rich, and when I go into first and drive at low throttle my AFR's go extremely lean. :(

I just came back from driving it. (Note I haven't soldered it yet.) And it seemed to be driving normally, except for idle. (Idle was rich.) **Maybe one of my IC couplers isn't sealing, I'll check them.) I'll post back after I solder up the wire. :) Would a high Hz reading also be because I...

Also, if it helps narrow it down better. I'm getting high readings on the karmen at idle S-AFC say 55-80Hz jumping.

Okay, To test, I just took the wires and wrapped them tightly together and tapped. I'll be getting the iron in a minute. But to see if the crimp had any change or not I tried this. Still no difference... :(

Thanks for replying. I would have soldered it if I had an iron. :) Definitely will take it off now to try it. Would that really make a difference?

When I swapped the AFM sensor, I used an 87. I have an 89 ecu and car... Is it possible that the computer can't use the 87 sensor, and my 89 sensor is trashed?

I just developed a serious problem with the 7M running. It started yesterday when I removed all the IC pipes to flare the ends. Since I am so used to taking everything off, I forgot to disconnect the harness to the afm. I noticed this of course when I went to pull the intake away, I felt...

Who here has gone **half wave** then take your hand down when you realize it's a BMW 850ci? :rofl: Those bastards always fool me.
