Rear Cylinder Lean At Idle - NEED HELP

Rear cylinder runs extremely lean at idle 0%tps. The slightest increase in tps and the readings are as expected. The rear cylinder at 0%tps will be 14.5 to 14.8 regardless of how high I set the VE tables. The injector pulse is 3.0 for the front and 2.25 for the rear. It appears to be something in the electronic system. The front cylinder will be at the AFR command rate 13.8. The minute the TPS is 2% or above the rear cylinder afr is at the command rate. I have no clue as what could cause this. The engine also has a tendency to run hot at ilde - even with the rich afr command mixture.
