Just brought the integra to get a sticker and it failed for rust and emissions.
On the emission the numbers that failed are the

CO grams per mile Reading 70.59 Limit 30.00
Could this be wires, cap and rotor, I already did the plugs, mpg has been crappy since it doesnt really warm up while driving(thermostat?) or an 02 sensor

ANy advice on how to bondo a hole under the rear taillight?

Thanks
