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?

Hum, I thought all '10s but fleet cars had the A6.


Anyway, the A6 does help a little due to better gearing, but the A4 is IMO a smoother tranny. The I4 is underpowered for such a size car and that is just the nature of 169 HP in a 3700 pound car.
Agreed, Silver. I've driven '09 & '10 Malibus with A4 & A6 trannies, and the A4cars seemed to ease into the shift changes better than the A6. The A6 seems to shift down in the lower gears a bit harder than I like, definitely more noticeable than my A5 in my '98 F150 did. I KNOW Chevy can do better than that.

Much of the shifting quality stems from the programming Chevy has applied for the transmissions. Maybe some can come up with a better tweak.... ?

I don't notice any power draw on my I4 w/A6 with the AC on, but seeing that I use it 10 months a year in Florida... I dunno. Been a while since I ran without AC!
