Choke issue when on tick-over.

Postby e30 baur » Thu Aug 28, 2014 7:33 am

I have a 1984 323i and recently got a few bits sorted including timing belt, warer pump, etc. on a cold start the choke results in the engine revvi g at about 1400. Every 2-3 seconds it drops to 900 and then goes back up again. Any idea what is causing this. When the engine is warm it idles sweetly at about 850 constant.

Could be failing ICV, I don't recall if 323s had them, or the cold start injector?
