ok so here's the thing, like 95% of the time, my car takes about 20 seconds to fully accelerate. no matter how much i press on the accelerator it won't speed up and when it does it jerks then speeds up and there's no problems. it does this every time i break and start again. it's had a tune up, the hose connecting the gas was changed, the engine was flushed it has transmission fluid and i don't know what else could be wrong with it.
