My engine light has been on and I checked the OBD with the computer at Autozone, It reads small evap leak.

I changed the gas cap and the Three rubber fittings going into the intake (they were original and dryrotted). The light has come back on, any ideas??

 

Could be any number of hoses in the system or a small hole in the gas tank. Being a small leak the hole could be as small as 0.04". The best way to find it is a smoke machine. You have to close the vent/purge valve in the evap system then fill the system with smoke and use a good light to see where it comes out. I highly suggest a shop.
