Can gas pedal on newer cars be adjusted to have more resistance ?
Not really. There is no adjustment and the pedal is not even connected to the engine with a mechanical cable anymore. A clever tech could probably rig up an additional spring in the pedal assembly, though.
I donāt think so, and I wouldnāt want to mess with it, what if the āadd-onā jammed?
thereās no way I would agree to modify the accelerator pedal . . . I suspect a lot of the other professional mechanics would also refuse

Thank you for your response I am hoping where pedal pivots on a bolt bushing with some sort of spring can be added or changed.
I know what your saying Iām going to a guy thatās been machanic for 30 years hoping a spring where it pivots on a bolt or bushing can be changed.
If that is the case, I would be more inclined to change out a part rather then add anything that was not intended to be there. This has to be a concern voiced by other owners as well. It might be worth a call to a regional representative or the factory for a little tech advice. I might visit the parts department at your dealership for a diagram of the linkage involved.
I donāt see why not. Itās probably already using a reverse tension spring to return the pedal up, just make it a bigger spring. That wonāt mess with the electronics, so long as you donāt change the āReleasedā position.
Itās drive by wire, right? May not be an easily accessed spring.
Ever hear of liability . . . ?!
If you modify the accelerator pedal and an accident occurs, I imagine that would be an attorneyās dream come true 
Hereās what the accelerator pedal/position sensor looks like.

Itās an electronic component that I wouldnāt mess with.

Yeah. Fuggedabouditā¦
Make sure the spring thatās supposed to be there hasnāt fallen off. The spring on my Corollaās clutch pedal fell off; either that or it was never attached to both mounting points at the factory in the first place.
Thereās no external spring, looks like.
Just curious, with no spring, what makes it pop back up then, when your foot releases the gas pedal? There is a spring, but it is inside an assāy and canāt be accessed?
Ya think George?
Or doncha?
