Why does my 2000 grand am idle rough?
I recently installed me plugs and plug
connectors. Thoroughly checked all
vacuum connections for leaks. Only idles.
Rough when in gear (automatic
transmission) any help greatly appreciated..
Double check that you got the right plugs and the correct gap.
installed me plugs - "ar matey". Rough under load - like BoholMark said plus air filter,plus dirty injectors,plus,plus.
