I have a Injen CAI and i just installed a Crawford PLenum 2 days ago and tonight sitting at the staging lane at the track my service engine light went on. i feel like it is the O2 sensor reading to much air coming in.... but im not positive, can anyone give me some advice to go about this?

 

First call Doug( Crawford ). He will gives you some mistakes that most people tend to make. But here are few things to look for. Make sure the nibble( black plastic ) is put back on after the installation. Make sure all hoses is tighten. Make sure the black circular plastic that goes under the oil cab is not stuck between the upper and lower plenum. Well there are many more , but like i said call Dough. Good luck.

 

thats what im gonna do today, thanks
