I have a 1999 Dodge Avenger with the check engine light on. Code comes back with emissions gross leak. I changed the gas cap and reset code but came back on. I don’t see any gas leaking on the ground either. Any suggestions?

You must mean the EVAPORATIVE emission system? We fix many problems with these EVAP controls and the hoses that connect them on Chrysler vehicles. Each hose from the charcoal canister to the fuel tank must be checked for cracks. The purge control solenoid is another common failure item, but if your only codes are for gross or large leaks, a bad hose is more likely.
