car trouble

[xs042sx]

i have a sr20det blacktop s14 and when i turn on the ac its hot sometimes when im stopped and when im driving and go to down shift or put in neutral the rpm drop all the way and the car shuts off.



help please.

your ac probly gets hot when you sit because your engine isnt turning as many rpms as it would be when your driving so the ac compressor is not effectively cooling the incoming air as for the car dying my car does the same thing but i need a tune pretty bad so im not sure about you
