i drive a 2007 LS manual. whenever i have the air on it feels like i lose power. it takes longer to get my RPMs up and when i shift, the clutch/gas pedal timing is different. i know running A/C will decrease power but i also know it shouldnt be this bad. anyone else with this problem, heard of it, any ideas? please help me out here

 

more than likely its normal but you could try cleaning your TB. JUST DONT OPERATE THE BUTTERFLY VALVE!

 

Perform some routine maintenance and it should help out (New spark plugs, clean the TB, new air filter).

 

I've done all three within the last 2 months, and made the mistake of moving the butterfly, so I even got the ECU reflashed at the dealership, and none if it helped

 

Yes... A/C dogs the little 2.2. Facts of life of owning a 4 cylinder. NA at least..

 

My LSJ does the same thing. Pretty sure it's normal. As stated above, welcome to owning a 4 cycl

 

um, lol, any car with the ac on is gonna dog it, my work truck is slow as **** to accelerate from a roll with the ac on and it's a 6. with an 8 maybe you won't notice it as badly, but you drive a 4 cylinder...lol.

 

mine doesent do it that bad, but I do notice a low humming sound recently now. if I have the AC on high i dont hear it, but when i turn the fan to 1 setting i hear it. When I turn the AC off, it goes away. This just started happening this summer, think maybey my AC clutch is starting to go or something?

 

sounds normal to me. AC robs power for sure and not just a couple. Your ac pump could be going out too. Maybe a bad bearing in the compressor or something idk

 

i moved the **** out of my butterfly valve, but it was removed from the car so idk if that matters

 

X2.....I also own a lsj and with the ac on plus it being hot as ***** the car isnt the peppiest. Every 4 cylinder I've owned have acted like this

 

my interceptor shows -21 vacuum at idle.

when i turn the ac on it drops to -16, and the engine load jumps up between 10 and 15%

pretty significant if you ask me

 

Yea i notice a difference, makes the car even slower. lol

 

Me too i just clean the tb and i moved the butterfly valve alot but i also took it off first and unhooked the battery. I drove around the block and car was great didnt see or feel any problems.

 

We are all acting like these cars produce a lot of power anyway.

 

They do make alot of power especially when you have alot of stickers and overnighted parts from japan. lol

 

windows down ftw

 

2-60 A/C for the WIN!

 

Noticed that even in the 2.4. Hated the extra revs needed to get going and the bogging, so I rarely used my AC.

 

this

 

Maintain steady throttle on a open stretch of road. Then, turn off the A/C. Its like getting a shot of NOS.

 

Ecotec just kicked in yo

 

You'll look like this

 

I use my ac from a 40 roll so I get tracshuns.
