I also installed those two solinoids on my '65. Like yours, they're not hooked up to anything other than the wiring harness. These shouldn't be causing your problems, I just ignore the smog pump codes as they don't trigger the MIL (check engine light).
You may want to check the voltage from your O2 sensors to see if they are in the right range. Also, I'm thinking your idle problem could be caused by the ISC. Also double check the EVP sensor has smooth voltage changes (like the TPS should).
Did you hook up your EGR valve?
