What Is Hc Gpm Emissions Fail. Web emissions or smog is a generic term used to describe certain harmful gases in the exhaust. Web unfortunately, it failed.bad it seems.
Fouled plugs would result in much higher hc due to misfire. Low compression would likely be. Hydrocarbons (hc), carbon monoxide (co) and oxides of nitrogen. Upon my first emissions inspection it failed because the hc. Reading was 19.2444 and limit is. Web general motors multiport fuel injection engines may fail emissions standard testing due to excess oxides of nitrogen levels in the exhaust gas.
