that's not really much of a diagnosis, is it?
if you can get to the o2 sensor and get a voltmeter to it... do it. take a look at the numbers going back to the pcm. get a $2 bottle of propane with a on/off valve and shoot some propane into the intake. see if the voltage on the o2 increases.
if it increases really fast... like in less than a second... your o2 is fine.
if it doesn't change or changes slowly (like .2v going to .8 volts in like 5 seconds), you go a lazy or defective o2.. then replace it.
