Yeah, it's the sensor. Same lights came on in my box when put in my intake but didn't hook the sensor back up. Hooked it back up, the lights were still on, drove it home. Came into find Squirrel's ECU Reset post, the link didn't work. Got in the box later that night and it was off.
The code was P0171. The ECU is very touchy. Depending on mileage the plugs are worn or the Air Flow Sensor got contaminated, there are small heated wires that collect dust. It can be cleaned with electrical spray or Brake clean and the battery disconnected and headlight switch turned on for 1 minute to reset the KAM(keep alive memory). If it's nothing the CEL will go out by itself within 40 cycles.
