Under center console on pass. side floorboard, there's a piece of carpet that comes off. Behind it there's a blue clip sticking on the side of some metal - pull it off. Then you'll see a purple harness clipped on that - pull that off. Then you take the paperclip and stick it in the 2 holes.

Turn the car to ON/ACC so everything turns on but the car. You're CEL will begin flashing, count the number of long flashes and short flashes; then put them together. IE: 7 long and 1 short, code 71. 2 long and 4 short, code 24. Find this out and come back and let us know.

Code 1 is your Primary Heated Oxygen circuit giving a high/low response. More than likely a problem with your PHO2 Sensor either being open or having a short. Need to check the wires, make sure one isn't loose. It is located on the downpipe right before the cat. Have you upgrade your header/downpipe in any way? Any "engine breathing" mods? ie: intake, header, exhaust, tb, im, etc.

Shouldn't matter the company. More air is going in so more fuel is going in. Could be that it's covered in carbon, but then you'd be throwing a code 61. I'd jack the car up and check the wiring on the sensor, make sure it's OK.

intake/ header/ exhaust doesnt mean more fuel.....the only way to adjust fuel is an adjustable FPR, injectors, a/f controller, and other programs
