just a thought, you could be pulling to much vaccum @ the distributor, either the spring on the vaccum advance canister could be bad, or somehow the vaccum line is pulling more than it should, causing you to have too much advance even @ idle.....not sure right off the top of my head how to check other than pulling the vaccum advance line off the distributor, & the rpms should drop back to normal, if not then you know you have a problem else where....
