Please help,my g-body failed smog,high Co and HC with pic of report!
Zup guys,I know this is not my trans am,but its still a gm and if there is a place for help,you guys are it when it comes to engines.So I took my 86 regal limited with the 5.0 307 4 barrel carb in to the smog station and the car failed.It's a Gross Polluter apparently.The car has new plugs(Delco .60gap)new wires and cap.New o2 sensor and catalytic converter.The car is also equipped with 13" spoke rims and tires(maybe thats also a problem because the engine has to be reved more to reah 25mph?) Anyway here are the results,very high in CO at 25mph and HC,what could it be?please help a brother out,thanks in advance.
