OnStar says I have a problem with my emission system
So I get an email from OnStar that says that I have a problem with the vehicles emissions system and to push the blue button and have the advisor run a diagnostic. I'm game and want to see what they have to say. I call and they run the test and say that everything is ok. Well then, no problem right?? NOT. I then hook up my Tech 2 and pull the codes. Yep!!! P0301; misfire cylinder 1 sitting in pending status. I pull up the misfire graph and see that the counter on #1 reached 75 which must set the code. If it fails the test once more then the MIL will come on. I also notice that #3 has 39 counts so it's creeping up there too. I am still under warranty but figured I'd wait until a MIL is actually illuminated to bring it in. What's the usual suspects for misfires on these engines? I have 58k miles. Coil, plugs, fuel inj?

I'm going to say coils, likely wiring connections.__________________________________________________ ________________
