Hi guys I just installed a short ram intake on my 2000 G20. And it threw the Check engine light. Now I know most will say hoses or maf sensor. But the other little sensor is concerned about it was a little hose connected to it ram the the oem box so I pulled it out and just plugged it in but I started the car with out it the first time but after I put it on it didn't go away I unplugged the battery a few times still didn't go. Any suggestions? All the hoses seem tightly fit as well plz help!

I'm sure you've resolved this by now, but did your intake change the diameter of the maf housing?
