The light is located next to the gate adjar light in the upper left area of the cluster. It at the 2500 rpm mark on the tachometer.
I would take the vehicle to your local Auto Zone and ask them to scan your car for trouble codes. The will scan the car for you at no charge. Write the codes down and respond back.

take about 20 minutes if you have to tools handy. You have 4 02 sensors so be sure to have the tech tell you which one.

EGR is maybe stuck open. disconnect the vac hose at the EGR valve and see if the idle smoothes out. If the EGR is sitcking open, thats a vac leak. If that fixes it, replace the EGR solenoid valve.
