I just bought a intake off of ebay. It is the k&N filter with the piping. I have all the plugs and tubes hooked up but my engine light keeps coming on. What do I do to fixed that? Will it be a problem?

 

Did the light come on immediatly after you installed it?

Did you start your car with anything disconnected?

Pull the codes from the ECU (read the FAQ at the top of the 4th Gen forum) and post again, or do a search.

 

Did you plug in the sensor that goes at the bottom of the pipe.It should be where the hoses

 

The two sensors are both put in. Also all the tubes are conneted. I can't figure out what is wrong. I didnt' touch anything else.

 

pull the codes off the ECU....

 

Then what do I do when i pull the codes. I have no clue....

 

well count the blinks, and post the code here...ill help you out
