i just change my intake and my check engine light comes on why is this..

 

Because of the MAF Sensor. Use the search funtion.

 

If you put on a CAI it will read as a knock sensor and O2 sensor probably. Read the FAQ at the top of the page to find out how to reset the ECU, it's pretty easy and takes care of the prob. If light comes back on again though, have it checked out.

 

i think you forgot to connect the little sensor things......what kind of intake did u purchase??? some universal intakes dont include the holes and u have to drill them yourself

 

i have the place racing intake...no problems till this day ... juss watchin my fuel level go up and down from floorin it !!
