I recently changed the plugs on my car because i was told that was why my car had a loss of power particulaly when i would go up a hill. Anyway changed plugs i was carefull not to cross any wires and did one plug at a time. Since then my car seems to run roughly and when i sit still at a light or something it feels like the motor jumpsl. What could i have done wrong.

Is the plug gap correct? Also it's possible to have actually cracked a plug while installing it, seen that before. Did they seem to go back in easily? And last the wire may not be on securly enough on one of the plugs.
