However, I can bring the idle back to 700 RPM by agressively "tapping" the accelerator pedal. The engine idle returns to 1100 RPM after normal driving. Also, if the engine is shutdown and restarted, the idle always returns to normal (700 RPM). I have cleaned and lubed the throttle blades but have not removed and rebuilt the throttle body. I'm also wondering if the throttle linkage may be sticking and causing the issue.

Any ideas?

The fact that it idles fine after shutdown says its a sticking throttle. I just went thru same issue although my throttle body was disassembled for media blasting and paint.
