Question: Looses power when accelerating

Randomly when accelerating the car just does not obey and the rpm's do not go up and it does not increase the speed.

Randomly RPM's go up and stay abou 20k and will not come down even in neutral or park.

Sometimes when i start the car it makes a knocking noise and sometimes when i don't hear the noise if i put in drive i does not go I have to put it in park and let it knock and then it's fine.

Changed spark plugs.

Battery was disconnected for a few days could the idle be messed up?

Some mechanic told me I have to change the computer.

I get code 21 low voltage TPS sensor - tested the sensor and it looks fine.
