Chrysler Repair: check engine light, vacuum leak, pin hole

Question
The computer says I have a large and a small vacuum leak. I put a new gas cap on and my mechanic has sprayed ether on the engine and on all lines under car. No leak detected.
I clear the codes and light comes back on within 10 miles.
Help please
