It feels to me like the gas pedal on our 07 TSX (AT) is a little stiffer than I am used to? Is this something that can be corrected (Throttle body cleaning, cable adjustment) or is that how it is actually supposed to feel? The pedal feels a little too heavy on take off.

 

I haven't had my TSX for too long, but the system is drive by wire, so a bound up throttle body shouldn't be a problem.

I would guess that there is a cable going from the gas pedal to the accelerator position sensor.

 

I haven't had mine for too long either. I have driven an 04 TSX before and I don't remember it feeling as stiff as mine.

yes, There is a cable going from the gas pedal to the accelerator position sensor.
