i am about to own a 1982 vw rabbit with the 1.7 liter gas with a possible CIS fuel injectoin system. we are having some issues with fluttering in the engine can anyone help? we just got it running after cleaning the fuel injectors changing the spark plugs and fixing a hole in the fuel line. could it possibly be the distributor or the fuel injectors?

also has anyone seen a place to find a alternator relay for a decent price. the cheapest i have ever found them was $125.

Thanks
