Hi there,

Fairly common complaint these days with many late model vehicles with electronic throttle control.

Some cars are worse than others, the dealers will say normal operation.

You could try adding a device like this, or a chip tuning dyno shop may be able to program the "softness" out of it.

Hope this helps.

Expert:  Gary replied 3 months ago.

I would find a tuner of your vehicle, and explain to them the situation.

They should be able to tune out a predetermined amount of throttle lag in the PCM program.

Then there is no piggyback added parts to fail.

Hi again,

How did you go with your problem?

Throttle body operation looks at pedal input as a request, the PCM opens the blade at predetermined rates, depends on many factors.

I hope my advice has been of assistance to you.

Kind regards
