HC stands for Hydrocarbon, a substance in your exhaust emissions. Smog and emissions tests measure the amount of HC that your car produces. High HC readings may indicate poor fuel ignition. The causes are numbered and varied. Anything from bad spark plugs or ignition wires to vacuum leaks because of a failed gasket can cause high HC readings and hinder your engine’s performance.
