Corona 1988 Idling problems

Hi Everyone

Can anyone help the new guy? My 88 Corona has a problem that has been coming and going for a while but is consant now. When cold she starts fine
but as soon as she is warm she does not want to idle. When she cuts out,
she will not restart untill she has completely cooled down. Even then it is touch and go. :banghead: Of all the ideas so far, a faulty O2 sensor sounds good, but who knows. I would appreciate any comments.... Thanks everyone!!!!!!!!!
