#1

my wife has a 2004 dodge durango, and a couple of months ago the check engine light came on. I took it to my local auto parts store and had them check the codes for me. They are as follows:



Troubleshooting P0441

1-Defective or loose fuel cap

2-EVAP canister or hose cracked-not connected

3-Purge or vent solenoid defective

4-Vacuum leak at engine



I checked the fuel cap and even replaced it. the light went off for a little while, and the came back on.

And now there is what sounds to be an exhaust leak coming from the drivers side of the engine compartment. Is this a vacume leak? If so, where do I look, how do I fix it? Any suggestions will be greatly appreciated!!
