Hi I just bought a Galaxy 2.3 Ghia X 1998 for my family, it has a slight problem, when its started I sometimes hear a relay firing like a machine gun and once started if i plant my foot to the floor fast it pops and seems to miss a little, when driving its fine if its over 2000rpm below that it does the same miss firing. I checked the coil pack and plugs, checked relay 30 as I know this can be a problem but all looks fine? Any ideas?
