hi, my partner recently purchased a mitsubishi space wagon 2.4 GDI 2000 due to us needing a 7 seater for the kids, its now making a noise when its accelerated in all gears but is worse in 3rd 4th and 5th, it sounds like a tractor (a very loud tractor)!! i drive a citroen xsara which had a simalar problem but only did it occasionally, i found out that the xsara was running on 3 cyliders as the coil pack (ignition coil) was breaking down. does anyone know if this could be the same problem as a mate said he thought it was the cat going. thanks
