Check engine light on? What plugs did you use? When did this start?

 

Yes check engine light is still on. Sometimes it will go off then start flashing. I used autolight iridium xp spark pliug. After changing plugs and coil it runs great till it heats up. I was thinking a leaky fuel injector on cylinder 4
