Hi guys ,
I just hope that someone could help us with the idle of my '75 2.0. I have the car for almost 7 years now and idle was always a little bit too high. We have been trying to correct this but it got worse instead of better. We changed the distributor to a 123 ignition, we changed all the vacuumlines, the AAR has been cleaned out and the idle screw is completely closed. The car starts at 1600rpm when cold and once it is warm it goes to 3000rpm and the idle stays there. The car pulls very well , a lot better better than when I just had it.

AARs are available. One sold here just a few days ago. Big thread on testing and maintaining the a few weeks ago. If can find, also indicates comparable Nissan part #.

It progressively closes as an internal heating element warms up, versus an electric valve would be open or closed. You can also take an AAR apart and may be able to free up the mechanism. There's a you tube video on that. |

There's a you tube video on that. I've seen the youtube video. I cleaned out the AAR a couple of months ago and it closed when I put current on it. My mechanic already took apart the AAR 2 times several weeks ago,apparently with no result. We'll see next week when the throttle is repaired.
