Having all kinds of trouble, essentially with even fuel delivery to all cylinders, in a '84 Mondial. Resulting in fried cats and failed emmissions tests. Anyhow, the injectors have been replaced, now moving to replace a more proximal and quite expensive part which I can't name, but apparently basically splits flow? Anyhow, wondering, first off, what it should cost to essentially replace the entire fuel injection system with new, stock components. Second, wondering if, as lon as I'm sinking a couple grand into the fuel injection system, if there is a more modern setup I should consider to replace the stock?
