Help with 2011 Chevy Silverado Check engine light
I have a 2011 chevy Silverado 5.3 liter. I bought the truck with a k&n air intake and do not have the ability to put stock back on it. The air filter looked dirty so I cleaned it and the check engine light came on. I checked the code and it said that there was a cylinder misfire so I replaced the spark plugs and wires, I rode around and again the check engine light came on and said it was the fuel pump, I turned off the code because the truck runs really good, the check engine light came on again. I ran the code and it said that the engine is running to lean so I took off the MAF sensor and cleaned it but again it came on. Every time I run the code it seems to be something similar leading to the air intake, I didn't have this problem until I tried to clean the air filter. I checked the entire intake and everything seems to be on properly and tight... Does anyone know what this could be?
