2.4 liter power with A/C on

My car has a serious lack of power with the A/C running. I have the 4 speed trans. It seems like I almost have to floor it from a stop sometimes just to get it going. Is it just the nature of this engine/trans combo?

I haven't driven a 6 speed 4 cylinder. Is it any better? Anyone here with a LS 4 cylinder/4 speed have this issue?

With the A/C off it runs much better so I'm thinking that if I complain to the dealer, they won't or can't do anything about it.

Any thoughts?

Unfortunately sluggish is the nature of an underpowered car with such widely spaced gears.

Honestly though, the A/C probably only eats up about 10hp when it is running... it's not that big of a deal.

Also, I didn't know that the 4cyl/4spd was still available in '10.
Only the LS got the 4 speed. 1LT, 2LT, LTZ got the 6 speed.
The Ac does load the 4cyl 4 speed,
it is noticable,
but flooring it is not needed to get going, just a little extra .

you may have an issue it's worth checking it out if only flooring the gas gets it going.
I dropped by the dealer today and drove a LTZ 4 cylinder 6 speed. With the A/C on there was a SLIGHT increase in take off power compared to mine. It wasn't really enough of a difference that would make me regret not getting a 6 speed.

As far as my car I don't have to FLOOR it from a stop with the A/C on to get it going, just a little extra pedal has to be laid in is all.
