I’m getting a cylinder 2 misfire code. Ive changed the spark plugs and coils, reset the check engine code and it still comes back after a bit. Only other piece of information I have is that it does idle too high when first started, between 1500 and 2000 rpms for a little bit until it gets warm but then it doe settle down to 1000 or under

 

cylinder 2? is this for the CX-7 in ur profile? u didn't state any information on the vehicle in question. but since u came to an rx7 forum, i'm guessing it's an rx7?
