okay! well tonight i was trying to hook up my HID kit but ran into a problem. on the instructions it says to change your fuse to 20's well after i did that i started the car up and noticed it was running really weird. The rpms started rising on its on and the check engine light came on. Swtiched the fuses back to 15 and still have the same problem. The car idles weird... when i take off it putters then starts to go.....

could it be a spark plug? Im lost.....

Car is idleing a little over 1k rpm....
