I thought that starting in 84, they got EEC-IV, but the owner swears his has EEC-III. did some early 84's in fact, still use EEC-III?
Yes. Some early 84's sold in California were EEC III. There was a member on here a couple of years ago with one. He lived in California. He believed the reason was the delayed approval of the EEC IV for California emissions.
that's weird, because EEC-IV was "cleaner"
Was just the EEC-IV was not yet approved, how a bureaucracy works...
