Well did you take the compression readings when the engine was hot or cold?
Maybe you should check the compression readings again after flogging the
engine and getting it hot again. That said I dont think that you will be
having this problem due to compression. Sound more fuel related. Have you
checked the resistance of the coolant temp sensor? Is the air flow meter
good? How about your ignition timing settings after you replaced the idle
switch?
