Jphilipson,
Do you believe a host can go through 100+ peoples code (per server) plus his own and make sure that there will be no issues? Its simply not possible to run down every error or hack in everybodies code. Now yes your host should be able to give you an idea of what actual page or scripts is causing the probelm as they can see what process is taking so much of the CPU. Also read the TOS sometimes its against the TOS for the host to actualy mess with the code or site the only thing he can do (because of the contract) is suspend or unsuspend accounts. (along with create and terminate) Now I am not saying that poor support is justified I am just saying make sure you try and comminicate to your host the issues and ask the questions your being asked here.
