It depends what it is if it is an issue like a cylinder head gaskets or valves it is over $1500.00 to fix you really need to see what is the cause of it only running on six cylinders. It could be a lot and with the mileage posted I would say a bunch, but I have not seen it. See if the person will allow you to take it to a mechanic to check it over. It is well worth $50.00-$100.00 now than to be stuck with a large bill after you buy it. It could also be a bad engine which would require replacing or overhauling which can run quite high.
