Id just like to let you guys know that the problem was repaird. I was thinking it could be the 02 sensor, but not as bad as a faulty 02 sensor should happen. Anyway i went through and ordered a ZR1 3 wire 02 sensor, spliced up a couple of wires and problem went away. At idle it at RICH,but after 2 min. I can see the pointer on the Air/fuel gauge move at a time towards lean,but idle is still fine...
