Im a little stumped here. Have an 09 with a 4.6 that's throwing an evap code no gas cap. Its also throwing a engine temp sensor code. She is running a little cooler than usual. All of these problems started after I had a coil go bad. Any suggestions?

There is an extensive system of "gas vapor recovery" hoses that are designed to prevent gas vapors from escaping into the atmosphere. If one of these hoses were knocked off during the coil repair, it can give you a code. I would check the gas cap and filler neck first. Ithe there is any signs of cracking in the rubber seal, replace the cap. It is not unheard of for the filler neck metal to have a small crack as well. A temp fix in that case is a dab of silicone until you can replace it. Look carefully at ALL the hoses under the hood for cracks and damage. good luck
