1988 900S, 16 valve, 5spd, 177K miles
I bought a used AIC valve on ebay and installed it on my 900S to hopefully resolve the erratic warm idle problem. I was told that it was tested and in good working order. The cold start jumped up over 2000 rpms and then the idle went erratic between 1500 and 2000, revving up and down in this range with the engine cold. When I revved it up it stalled.
My engine never revved up and down between 1500 and 2000 rpms when it was cold with the original AIC, and it never stalled out. This used AIC replacement seems to be making my engine idle way jumpier than my original AIC. The Bosch numbers match. Did I get a used junk AIC valve?
If the AIC is working properly and I decide to purchase and install a new one, should I have instant good results? This used AIC valve seems worse than the original one!!! Thanks for your help and input with my ongoing idle saga!!
