Car jerks hard when i tap the gas
NOOB here
This is my first manual car and first sports car, so i'm not sure if this is normal...
Basically, if i'm in gear and let go of the gas, then i tap the gas pedal, the car is very unsmooth and kinda jerks. it's also pretty jerky if i let go of the gas and press on the gas again, but if i tap it it's really bad.
Is this normal?

Have you been driving a newish car with throttle by wire? The throttle response of these is beyond bad. Since the computer has to decide if your throttle request fits in with the EPA's plans, it can take a very long time between when you step on the gas and when the engine actually wakes up. This leads to a tendency to really nail the gas just to get any response at all. On the other end, throttle by wire cars hang on the throttle when you lift off the gas. You have to drag them down with the brakes. This helps emissions on overrun, but means there is no engine breaking effect at all. In comparison, the S has lots of engine breaking. It slows down quickly just by backing out of the throttle.
As an example, at 35 mph in a Ford Fusion, you can floor it, count to three, jump off the gas, count to three and then return to the normal throttle position, and NOTHING will happen under the hood.
Your S on the other hand will try its best to do just what you tell it to do. Once you get use to it, you will really enjoy the responsiveness. Other cars will feel down right numb.

I test drove DBW S2000s prior to buying mine and they exhibited none of the issues you described. The OP's seems to be describing related to the fact that his car is MT and this is his first MT car. The torque converter on an AT car will smooth out the effect of engine response.

i'm glad to hear it's not something wrong with my car.
daily driving it's not too bad but i'm kinda prepping myself for a few track events this season and i guess i'm just not used to it. some of my turns were very jerky because i kinda tapped on the gas (not sure why i did). but anyways, more practicing for me i guess

Well the S is such a torque monster you gotta expect that. You'll also find that a low speeds you may have to feather the clutch to keep the car moving smoothly.

Clean the Map Sensor (unplug and remove clip from throttlebody for cleaning)... Then pull the 7.5 ECU fuse. The car is not suppose to jerk by tapping the throttle. I bet the jerkiness will go away.
