try this on your car

I never tried this before, untill today. I hold the gas pedal at a constant pressure in neutral , i notice eventhough i'm holding the gas steady, the rpms is slowly bouncing around 2-3k rpms.

It will jump naturally but not a full 1000 rpm difference. I think its more like 300 or so, and there are other variables like your foot not staying perfectly in place and whatnot

the reason i think why it just bounces around 2-3k is because you're only giving it enough gas to make it go to there, the more gas you give, the more fuel goes to the engine to make the rpms go up. i think thats right
