Check Engine Light
My check engine light came on this morning on my way to work. When i started her up this morning it was 27 degrees out and she was really idling rough. Let her warm up and as the truck was warming up i noticed the tachometer bouncing- the engine was idling up and down.
Now i have two ideas -
1. I've got a bad tank of gas, however I'm about 1/4 of the way through this tank.
2. I'm running a Fram washable air filter that I washed and dried this weekend.
The owners manual says to wait through 3 cold starts to see if the light goes away, I'm thinking about going and buying an OBD II scanner.
Truck has 37,000 miles on it and is a 4.6L 2006 Supercrew.
Any thoughts or ideas?
