Pontiac G6 Forum : “There is a hesitation/lag when first pushing on the accelerator. Is this common...”

hello, ok no that is not common, and yes the dealership can repair the problem, i take it the car is still under warrenty? if not i would take it to a reputable shop, save some money, the dealerships are much higher with parts and labor.

depending on the level of hesitation/lag, i know some cars have that as a safety feature so that when you take your foot of the brake, the car won't roll backwards and you have to take into account the heaviness of the vehicle for its build. Pontiac wanted to avoid having their customers pay a gas- guzzler tax so they made the car a lil heavier. Have you noticed a difference since you first bought it and now?

yes that is normal if its only for a split second because there is no cable between the throttle on the engine and the accelerator pedal it is a "drive by wire" vehicle the throttle has an electric motor that is controlled by the pcm.  its also how they control the traction control now, if the tires are spinning the pcm reduces the throttle opening.

OMG , my G6 dioes this and I took it the dealer twice and they could not explain why it did this , but now I know !!! I was so upset because I finally got the car of my dreams and then I thought I got a messed up car , but now I understand , thanks for letting me know about that !!!!

Try running 2 Bottles of seafoam through gas tank and 1 1/2-2 through brake booster it will be like brand new repet every oil change or so

Along with it being an electronic throttle, the over done air baffle on the air intake, tends to slow air flow to the engine.

Suggestion, Cold Air Intake.

I have had this happen once or twice. But it was freezing outside and the motor was not warm. Its never a great idea to romp on a cold engine. My advise is Zmax. Its great stuff and its not like seafoam is smokes a mo fo. Simple to perform, best done at the time of an oil change.
