My Volvo was misfiring so I replaced the spark plugs. Now it's worse.

I was having a misfire code in cylinder 1. I changed all the plugs and the ignition coil on cylinder 1 and it's acting even worse. It's puttering. Sometimes the lights on the inside start flashing. I replaced everything the same way it came out of the engine but I must of messed something up, right? Why is it worse? I drove it a mile then pulled everything back out to see if something looked off but it all looked fine. Please help. Thank you
