What sensors to replace?

Hi all I've had a problem with my car leaning out at warm idle! It leans out to around 16.4-17.0's.

It's fine from a cold start and when driving it's just at warm idle! I've been putting it down to lambda sensors but I've replaced them and it still happens! I'm in the middle of deleteing the stock sensors and using a AEM wideband instead by connecting it to the greddy e-manage.

 

It's a 1993 NA-T. However I could of had this problem before I went NA-T but I wouldn't on known as I didn't have a wideband in place to show me.

 

So my question is: could there be another sensor causing this to happen! And witch sensors could it be? I will just replace as many as I can if I know witch ones to change.

 

Thanks in advance ;-)
