Drivability and idling issues

[gtcoup]

i have no idea where to post this, or really a good way to explain this problem im having. once and a while cruising, light in throttle, rpms around 2500-3000 the car seems to almost shake butif i let off and get back on it it stops... it feels like the engine or teans is shaking idk. itseems like its when going 30- 40mph...... also. someetimes when i start the car it will rev high and drop low down to like 400 and almost die, rev, drop and then go steady. today it happened and it died. started back up and was fine. wtf

edit.
i read my own post and im like wtf.. im way to high and dumb sorry.
