Hi there. I have just installed new headlights in my 08 Subaru wrx. In order to do so, I had to remove the battery and the K&n Intake. After I was finished, and hooked everything back up, I notice a significant change in throttle response. If i just touch the gas, it doesn't do anything. Before, when I touched the gas pedal slightly, the engine would rev. What happened?

p.s Are 80 watt bulbs safe...?
