Throttle Response

I just purchased a 2011 Chevy Cruze LTZ RS. I've noticed that on take off the car hesitates a second before it goes. Example: pulling into traffic is very dangerous because when I floor it the hesitation sucks. Is anyone else having this issue?

I found my plugs were between .021 and .024
Since the factory recommendation is .028, I changed all mine to .032 (split the difference with .028 and .035)
It noticed an immediate improvement in the idle. The acceleration was better as well and didn`t seem to need to shift down or gun it to get going.
I suspect my mpg will improve with this 15 minute adjustment too. (I didn`t realize hoe easy it was to remove the plugs on this engine!)

Thanks for the tip!
