See where the idle settles when fully warm, in gear.
As you get familiar with the WinALDL look at the data several times and capture it or takes notes to see if the readings are consistent when you reach the same conditions. I would like to know if it runs on the cold side all the time and if the voltage is always hanging low. Look at the oxygen sensor voltage which should jump all over under one volt. I want to make sure it is not reading on the rich end consistently while giving a rich command.
Have you ever had the intake off and looked at the build up on the valve steams. Have you ever used SeaFoam to clean buildup from this engine.

If it is modified from what came stock from the factory, let us know that too.
