I took the stock intake tube out today and took the baffle out of it. I put the intake back in the truck without the baffle in it and plugged the sensor back in. Went to start up the truck and the check engine light is on. Any ideas how to get rid of it? thanks

 

Did you check for codes ? It would help to know what codes were thrown. My guess is something with the sensor in the intake. Make sure the connection is tight.
