Strange how fanboys like to kick people when they have problems with their Acura and not help. But anyway, have not had this issue myself but a brief search on Honda Acura problem code dtc p2279 found.
"The ECT is the engine coolant temp sensor and will cause this code .Clearing then codes resets all sensors and drive cycles. The ECM update updates the ECM and changes the air/fuel ratio parameters which can fix this issue. Like I stated if there are no air leaks in the intake tube or pcv valve hose then updating the ECM would be next . "
"Sometimes cracks develop in air intake duct parts when pulling them off and reinstalling. Suggest going back over everthing you did during throttle body cleaning."
"Check PCV valve (stuck open?), PCV hose (split or hole), Purge (PCS) line, throttle body (was it removed? if yes check gasket), brake booster line, engine mount control solenoid."

"Looks like it may have been the map and or coolant temp sensor. After replacing the map it the surging reduced from 1000-1800 to 800-1100 so that helped and the coolant temp got it back to normal. I hope this helps someone. "

Hope you get the problem solved. By the way, changing ATF using only Honda brand every 10thousand miles was not enough to prevent early transmission failure on my 2002 Honda. Hope you will not get the bad outcome I did.
