hi all,

i have 94 v8 mustang. the issue is when i turn on the ac copressor, the stang performance become so lean, but the exhausts sound become more noisy. i believe that most cars when the ac copressor is on it will reduce a little performance. but i wonder why my exhausts become more noisy.

can anyone tell please?

regards

 

More noisy how? Well the car motor does have to work harder to run the compressor. A motor under strain will sound different. Your compressor may be starting to seize up if it really is that bad.

 

Check your compressor clutch.
