okayy so this is my situation my brother wanted to hear my new sub i put in so he went out n decided to start my car in freezing weather ( doesnt know anything about cars ) my amp wasnt on so he didnt know why it didnt work n shut the car off immediatly and ended up flooding my car my father went to warm my car up for me and found out it was flooded so he got it to start n i drove it to class completely fine no idle problems at all on the way back from class i had a little bit of fun in 2nd gear no problems rev matchd into it going about 40 shifted at 7k to 3rd no problem 10 mins later guy in front of me slammed on his breaks to make a sudden left turn i put car in nuetral n breaked n went around him then rev matched into 2nd gear going about 25mph thats when i felt as if the car was bogging down i thought i missd the shift at first and put it in 3rd same thing i was like oh no put it in 4th through each gear giving it gas would make the car shake n bog out pushing in the clutch would stall the engine i was about 30 seconds from home and made it there safely and turned the car off it felt as if i was dragging something i looked under car and nothing i started the car back up and it idled fine as soon as i gave it even a slight bit of gas the whole car plus motor would shake the car would start to die and save it self then just stall

anyone ? please

 

It could be any number of things.

compression test is in order
vacuum leak
tps kicked rocks
plugs need replacing
fuel filter clogged
fuel pump failing
pressure sensor failing
faulty ground wire
bad coil

It sounds possibly like limp mode? Check your omp and oil level.
I would suggest looking at the plugs and doing a compression test as a good place to start.
