Misfireing When Hot

[skidmark]

my every day bucket 1994 toyota camry has developed a problem. When it is cold it runs perfectly. but as soon as it warms up It misfires and has a flat spot??

I have replaced the plug,leads and cap. It has been compression tested and has 170 psi on every pot. Can some one give me some ideas on what else it could be

Which cylinder is misfiring?

Does it do it at idle?
