Default Engine misfiring need help

My 2014 Z51 just now started missing, sputtering, popping, etc....I have never had any problems with it....any ideas.....
Note....I did change my spark plugs last night....put all the wires back onto the right plugs....it cranked and ran great then all of a sudden started this....is this just a coincidence? Don't know what's wrong....

Pretty sure one (or more) of the wires is not properly connected. Check them all and make sure they are tight. Sometimes they work themselves off and this is what happens.

You pulled them by the boot right? Not the wires themselves which can ruin the wires.

If you have headers check plug wires to see if any are touching, they'll melt the wire once the car heats up.

I had put my car in my garage, came into the house to let the motor cool off so that I could check things out.....I came in the house and put this out to the forum.....
I went back outside and checked the plug wires onto the plug itself and found number 4 wire not on the plug...boom, I instantly knew that was the problem....evidentially I did not push it onto the plug hard enough...
Came in the house to check the forum input and BINGO..... you hit the problem right on the nailhead....
Thank you Sir for your input...going to the track tonight and everything is fine now....have a good weekend.....:salut e:
