Check Engine Light after Rain
So My truck has been driving just fine since I got it but for the last two days its been raining non stop. On Saturday night I was driving around, truck worked fine and most importantly, no Check Engine light was on. When I parked the truck that night, It had rained all night and when I went to start it the next morning, My check engine light came on and stayed. Other then the light being on, the truck works and drives perfectly. This is my first ever vehicle so any help or suggestions would be much appreciated. I plan on taking it it to shop but at this point I might have to wait til January. Is that taking a risk?
