Distributor blues

I have a JDM b16a in my turbo charged CRX si. I had to change my distributor and purchased those new Taiwanese ones. I know have problems when ever the car warms up and the idle speed drops under 1500rpm. It will run ruff until I push it. Does anyone else have this problem or know of a solution. This is my second distributor.

car just may need a tune up.
