1) I have 2003 Acura RSX Base (Automatic) with K20A3 Four Cylinder Engine.
I want to clean the Throttle Body with cleaner to make the car run better.
Is the Throttle old style where I can move Butterfly valve by hand to reach
the inner area for cleaning? Or is the Throttle fly-by-wire and controlled by
the computer?

2) Also, I plan to clean the electrical contacts in the car with CRC QD electronic cleaner.
Do I have to disconnect the battery for that?

Please let me know.

Many thanks!
