You probably have to disconnect something before you adjust the idle speed-the idle speed should be controlled by the computer-also look for a vacuum leak

Now it won't accelerate passed 35-45 mph, it also has hard starting when it's cold and I checked my manifold vaccum pressure and it fluctuates at idle and during acceleration,(vibrates).
