98 kick  works beautifully and have no problems...  but my damn service engine soon light is on and will not go off,,,,,,,  ive had it inspected twice now since then and nobodys got a clue...  it happened around 70000 miles

This light will come on every 50, 70, 100, etc miles. It's just the reminder to get the scheduled maintenance service.
On an older OBDI rig (1995 and older) there was a switch behind the dash to turn this light off.
On the newer OBDII rigs, there is no switch. What you will have to do is have a mechanic turn the light off by plugging a scanner into the computer. I have heard that if you unhook the battery for a couple of minutes, and then re connect it, this will clear the light also. However, this is not that reliable, and may not clear it.
