I have a nissan GX QG13 engine a/t they said it is only released here in the philippines.
I have problems with rough idling and engine really vibrates. Especially when aircon is on and when I am in drive with brake, or park or neutral.
Initially I changes spark plugs and the problem went away but after a month in went back. Pls. Help, any solutions?
