So, I have been having what I thought was the problem of a stuck-open AAR.
1. Start car cold 2. Car idles at 1800 RPM during warm-up 3. Car gets warmed up and now starts idling at 3,000 RPM 4. Pull input to AAR and you can feel it is still sucking air in (a ton). 5. Plug the input to AAR and idle drops to 950 RPM. Today, I replaced the AAR (thanks fellow 914world member) with another one. However, the problem/symptom persists just as above. So now I suspect I am not getting power to the AAR so that its little bimetallic strip can be heated up. Where does the power wire for the AAR trace back to in the car (74 2.0L)? How can I test that wire? |
