1995 XJ6 VDP 4.0L

My new baby is giving me some white (like I needed more!)

Car starts perfectly well
Iddles perfectly well
All coils are good
If I accelerate frankly it goes like a bullet
but if I accelerate slowly it is like the engine is witholding accelerationg properly

When driving on the dreeway at 70 if I let go slightly the gas pedal it is again tlike the engine is witholding power or gasoline
if I accelerate frankly no prob but if I accelerate just abit same problem it is not accelerating properly

Any clues anyone ?

My son plugged in is code reader the other day and we got these

P1316
P1777
