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.
