P0456 = Small Evap Leak
About a week ago I changed my cluster lights to blue LEDs. MrBigE noticed that my temperature gauge needle was reading a little higher than normal. Right below the half way mark. I've driven the car for about a week like that and I noticed that the engine was getting hotter. The needle NEVER went over half way but you can tell it's hot because at red lights there's "squiggly" wavy lines coming from the engine bay. Today the check engine light came on. I got a P0456 code - small evap leak. I noticed a small wet spot on the floor too. Looked like oil but I didn't check the spot because I was pulling out of the Wal*Mart parking lot. I don't know if all of the above symptoms (running hotter than average, CEL, wet spot on floor) are related. I read that the problem could possibly be a bad fuel cap. Any other possibilities? What do I need to do to repair the "small evap leak"? Thanks in advance.
