AFM Won't Respomd. Help!
4 Attachment(s)
I have a 1986 S4 N/A RX that I've been slowly getting to run since November. I've got it to the point where I can start the car but I can't drive it. The only way the car will start is if I hold open the flap on the AFM to let air in. I talked with a local guy that knows a little more about rotaries than I do, and he said the AFM is bad and I need a new one. I bought a brand new one (autopartswarehouse) and installed it and I have the same problem, won't start unless I prop open the flap, and if I take out the prop the engine dies.
Possibly unrelated, but it smokes A LOT when I start it (I've started it twice this way for a few minutes each, it never gets fully warm). There is no coolant missing and only a small amount of oil is gone so I assume that this is the infamous oil burning I've heard about since the car has been sitting around for around a year. Here is where I need your help. What am I missing? There is only one thing I can think of, and that is in the photo attached to this post. There is one wire missing from the plug in that goes into the AFM. Attached is a view of the afm plug in when it is attached. I did the test on the AFM as per the service manual (Page 4A 54, S4 service manual) and here is the results. E2 - VS (Suppose to be 50-500 ohms) I got 330 ohms E2 - VREF (Suppose to be 200-500 ohms) I got 280 ohms E2 - THA (Dependent on temperature, measured at 78 degrees F) I got 1721 ohms E1 - FC (Suppose to be ∞) I got ∞ Now for the flap E1 - FC fully closed (Suppose to be ∞) I got ∞ E1 - FC fully open (Suppose to be 0) I got 0 E2 - VS fully closed (Suppose to be 50-500 ohms) I got 310 ohms E2 - VS fully open (suppose to be 50-500 ohms) I got 84 ohms Suggestions? Ideas? I'm stumped. Like I said in the previously the car will only start if the flap is propped open, and if I take the prop out the engine dies. |

Will it stay running if you give it gas?
What color/smell is the smoke? |
Re: AFM Won't Respomd. Help!
Smoke is whitish color and I don't notice any smells. Engine dies if I rev high enough otherwise when I rev it sputters. Idling is perfectly fine other than the smoke. I'm not seeing any missing coolant only a little oil gone.

White is usually indicative of burning coolant, usually smells sweet. Gray is oil, black is excess fuel.
Have you done a compression test? |
