Drivers of some 2005-07 Acura RL sedans may complain of multiple drivability issues during unusually warm weather.
According to Acura, the symptoms usually get worse at higher altitudes, and are due to high volatility fuel leading to a vapor lock condition in the fuel rail.
Installing a new-design, recalibrated fuel pump and gasket (part No. 17708-SJA-A02) and part No. 17574-SDC-L01, respectively) should eliminate the trouble.
