Spark Plug Replacement Check Engine Light

2086 Views 5 Replies 4 Participants Last post by  Jb2007
I decided to change my spark plugs last night as it is nearing almost 100k miles (95k) and for preventative maintenence. I did everything right but when I started the car, I started it with one of the wires unplugged to the coilpack accidently causing a check engine light. This resulted in a check engine light and misfiring. I turned it off and plug it the wire back in and started it again and stopped misfiring but the check engine light is still on. Does this mean that there is still a problem or do I give it a day or two to let it go away on its own? Help please!

I bet it will go away. Drive it for a while and it should go off.
