Hi all... I have just started having a huge problem with my twin carb D15B4... Some times it runs fine then out of no where it will run rough while trying to drive and will only improve if I floor it... I just changed fuel filter and I'm guessing it could be a blocked carb? Or maybe coil on its way out? I really need some help... I pulled one lead off at a time and noticed 1 and 2 cylinders are obviously firing fine but 3 and 4 made hardly any difference at all.
