I put long tube headers and pro chamber pipe on my 2001 cobra I bought the eliminator and extension kit for my car but when i hooked up the eliminators and extension kit when i turned my car on the service light still came on. The problem was that the O2 sensor was running slowly does anyone know how i can fix this.
PLEASE HELP ALL HELP WILL BE VERY APPRECIATED

 

Did you disconnect the battery

 

Did you hook up the MIL eliminators to the rear O2 sensors? If you didn't then yeah you will still get a light. You don't put the eliminators on the front ones, cause those are used in your computer to calculate the fuel.
