Car won’t rev when rolling

[SmoothCat565]

Whe my car is coasting in neutral and I push clutch in and then let clutch out and then hit the gas, the TPS and engine speed dont increase as expected, but if my car is stationary and I do the same thing, TOS and engine speed increase as expected.

(notice very low TPS signal and much lower engine speed response) - this was performed while rolling I
