1983 Rabbit Convertible 1.7L gas FI
The engine is running very rough, with a pronounced putt-putt-puttsound, has no power at low speeds. On the hiway, it goes OK until you get to a hill. Plugs, wires, cap, rotor all new. Adjusted timing both ways, made no difference. Feels like the points are bad, but it has electronic ignition. Any ideas?
