I've noticed that when the motor is running and with the a/c on, the car trys to die, but keeps running, but will die if you don't apply more gas. Would this be caused by low freon, or somthing
else? I thought it may be the fuel filter but with the a/c off it runs fine.
Thank you

PS
Which line is the low side for putting freon in?
On mine there is a place on top and the other is lower down in front of
the motor. Is it the one on top?
