As for the quick cycle its more than likely because it is low on freon.
And yes your GT use's R134a.....R12 was outlawed many years ago.
Ok. Yes my AC is on Max and the blower is on max when I do it. The car is running. The gauge appears to be reading when its attached. It goes up to like 65ish psi and then it drops down to 8-10 when the compressor cycles. Ive had it sit like this for upwards of 20 minutes with me shaking the can and turning it upside down and on its side the whole time like the directions read.
