My boss has a 1999 sportage that he keeps at his vacation house in the DR. It needs new fuel injectors. All I know is that it's a 99' four cylinder and that it's not diesel. Doe sthat market have a different motor than the us market or do they use different injectors? If so where is the best place to get the injectors?

..?!?..changing injectors is an uncommon event here, but nevertheless these engines must be similar all around. THIs is basically a Mazda engine so I'd check for similarity but I cannot confirm at this time.
However, for the record, can you indicate the symptoms that point to the need of replacing the injectors?
