my check engine light came on twice today, i replaced 4 coils and spark plugs last month abd this morning i replaced the other two coils and plugs, about a half hour after i left the shop, my check engine light came on, went to auto zone and they said cyliders 1-5 are misfiring!! i have no idea what this could be?? any help will be appreciated

 

make sure that they coils are connected. check to make sure that the spark plugs are seated all the way in and tight. looks for a small spring inside the coil. u can see it if u flip it over and look where the spark plug sits in.

 

thanks man, im actually going too my mechanic in the morning, i just want too get a heads up with what could be wrong
