Parts identification
Would anyone be able to tell me what this is for? I’ve looked though the manual but can’t find anything on this. It’s attached to the intake manifold on a 79 California emissions car. The middle thing is what I’m focused on, would this keep my car from idling?https://cimg0.ibsrv.net/gimg/www.rx7...65ab4be104.png |
It would normally have a vacuum line attached. After some research looking at the parts fiche at Foxed.ca it turns out to be the altitude compensator.
https://www.atkinsrotary.com/store/7...61-13-770.html I am a bit confused why I am looking at a screenshot of your phone, and not just the picture of the part in question. I also see that you are on facebook. cool. Don't feel bad. I have never seen any tech questions answered on facebook either. I would assume that you could remove the compensator and replace it with a metric threaded plug. Anyone know the pitch and size? Being in Arizona I can't see it being that important. Someone correct me if I need put in my place. |

Mine broke, So I epoxied it. It does take time to get an eye for Mazda parts. I'm still working on that myself.

Altitude compensation could be important depending on where in Arizona the car is located/operated in. Along the Colorado river it's approximately 70 feet above sea level whereas if your in the Flagstaff area of Northern Colorado its over 12,600 feet above sea level.

You are correct, but long term adjustments would be necessary. I lived in Flagstaff when I had my first 626 and it ran poorly because the altitude compensator was an additional piece for cars shipped to higher elevations. I can imagine that would be exacerbated in a rotary, but it may not.

Yea, eye live in Phoenix but I’ll be up in flag every now and then. My car was running great but it started acting funky, eye would try to adjust idle speed and it wouldnt adjust with the screw, (79 sa) and the spot where the hose connects up, connects to the idle air screw circuit. I’m pretty sure this has to be the culprit of my no idle |
And just for iteration, the hose was always connected up it wasn’t ever lose eye checked for vaccum leaks and found none checking with spray but eye started rooting out if the emissions stuff has just now became faulty with age |
Eye think you may be on to it. LOL
