If its jumping around in idle you should check you maf. For over heating make sure that your radiator is full.

If you installed a lid with a reusable filter the oil from the filter will sometimes get on the maf and screw with it

When you did the lid did you put a fernco (smooth below)... cause if it didn't seal on the TB all the way then you would be getting unmetered air and sometimes that will cause your car to surge like you described...
