The book sez any time either the TPS or the ISC are changed to initialize. Stig is the only one to replace anything like that for cause! This is one of those "no downside" procedures since it is (or should be) done at the factory and should not be required unless something fails or is replaced BUT if it is initialized, it just "resets" in exactly the same place. In other words, "It cain't hoyt!" Since I have vented the gas cap there has been no need to initialize. It was a grasp at a straw, anyway since NO ONE, no dealer tech nor Kymco USA had a clue what was causing the problem of surging idle, hard starting, no starting, high idle speeds and whatnot. The answer was developed HERE!
