i have a 2005 G35 Sedan, i have a problem whenever i turn my ac on the car just does not accelerate whatsoever. i can floor it but nothing. just wondering what it could be. there’s no codes or any check engine light, just charged the battery up thinking that could be the issue but still same issue. anyone that can help me out?

 

I would think your AC pulley is bogging down the engine because of a bearing issue or something in the pulley track. Take a closer look if you can!
