Occasionally, my car does not pick up speed after a stop at the junction. Stepping on the accelerator simply revs the engine to more than 3000rpm but the car still moves at 10-20km/hr. I've changed the transmission fluid and spark plugs but problem still persists. I've to pull over and restart the engine, and it'll be back to normal.
