Just like the title says... in the morning when i'm warming up the car, I press on the Acceleration pedal (in neutral) the RPM goes up to about 3 thousand and when it drops, it drops down to or close to 0? can anyone tell me what can be the problem?
MODS on the engine are- 1/2" spacer, JWT pop charger, oil and filter was always change at the dealer until it hit 16 thousand miles after that i've been testing out different oil could that be the problem? some one please help..

Im pretty sure that's normal, i have a lightweight flywheel and mine dose that all the time. Its just the flywheel decelerating, Do the rpms just drop low or dose the car actually stutter or stall?

yeah it does that(stutter/want to stall).. but i have the OEM flywheel and clutch with 44 thousand miles on it..clutch is still good..

and also there's an noise coming from the bottom or the engine bay of the car when it's around 2 thousand to 3 thousand RPM? is that normal

hey my dyno is some what close to what you have..

The car has a cold and hot idle. I have posted both several times.

The noise may be the throw out bearing?

Mine does this too, Mods are in my signature. I've hear that spacers will increase that though if they are not done perfectly as well. Did it start doing it when you put the 1/2 inch spacer in?

ya, more info please? Did it happen after you installed the mod? Did you do a ECU reset, so the car can re-learn your idle?
