Default How to Clean Throttle Body 2.5 Spec V Engine

I have done everything I can possibly find to correct our 2008 Sentra SE-R Spec V from bogging down when it gets warm. I have replaced the catalytic converters, MAF, two 02 sensors, removed the K&N air filter and replaced with a stock one. I have replaced the spark plugs and it still bogs or loses some power during acceleration after the engine warms up. I am thinking maybe the Throttle body might need to be cleaned. The down side is I don't know how to without having to relearn the thing. Can it be opened and cleaned without having to relearn? If so how should I go about this.

I am getting about 16-19 mpg and I should be getting much better than that. I did a compression check and I am reading 150 on all cylinders. Any help would be appreciated.
