88 stalls when brake is pressed????
Hi everyone,
I have an 88 coupe that I am starting for the first time in a couple of months. the engine turns over great, and idles fine. However, the cars stalls as if you turned the key off when I step on the brake pedal. Im sure the battery needs to be replaced, but I am getting 14.2 volts at idle (according to my dvom, not dash). Its almost like I am shorting out the ignition when I step on the brake. An ideas?????

I quite sure it is not a vacuum problem. the car dies as if you turned the ignition off. No spudering or hard brake pedal. seems like its an electrical problem. Is there anything in common between the brake light switch and the igntion? ground points????

Da Mail Man is on the right track with this. Try what he suggested. A large vacuum leak will stop the engine and it seems that is what is happening when the brake is pressed. See what happens and get back.
