I have a 2003 Durango. Now that it is cold out I start it to let it warm up before I go to work. Now my engine light is on. I had it checked for codes and these are the codes P0300 Multiple Misfire,P0303 Cyl 3 Misfire , P0305 Cyl. Misfire ,and P0455 Evap System Gross leak. Is there any thing I can check before I have to put alot of money into it?

Need to fix the EVAP leak first. That will help with your multiple misfires. Locate your EVAP charcoal canister. Make sure that the canister is intact with both hoses securely attached. Next check the EVAP solenoid (hoses attached, no leaks, unit not cracked). Regardless, you have a huge vacuum leak somewhere in the EVAP system.
