The check engine light came on and I had the code checked the code came up as(misfire on cylinder 2 detected) I changed the spark plug and the spark plug wire and the problem still exist. I swapped ignition coils around and the problem came back again
This problem shows up after the engine has been running for about 10 minutes. When the engine is cold it runs perfect any help would be appreciated
thanks in advance

A misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression. An engine misfiring can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
