No compression #2 runs fine

Hey yall. First post first mustang. Its completely stock. I decided since just bought the car. 160k 00 gt 5 speed. I wanted to do a compression test for giggles. And found one side perfect. The passenger side not so much. Had #2 read 0 and the rest are within limits ..just, 105-110 on either side of #2 but 160-175 on all the way on driver side. I unscrewed it tried it 3 more times and nothing. Its not smoking, running rough, it pulls good and when i pull the coil wire off #2 while running, it starts running rough. So its got compression. Any ideas?

Im sorry 165psi on #1 0 on #2 120psi on #3 i looked at wrong paper lol.

if comp was really 0, it would miss all the time.....redo your test on that cyl again.

Thats what i thought. I figured id ask lol. But i did put it back together, let it WARM UP, and redid it, but i read 155 in both the low ones, making 165, 155, 155, 150. And 165 175 165 160. It sat a bout a week before today so. But thank you for your help sir! Good tongo for boost!
