Check the codes for cylinder specific code, also with the engine idleing try unpluging the fuel injectors on at a time and the one that makes the least amount or no amount of difference is where the problem is. Once you find the problem cylinder/s the you have to test to see what you are missing, spark, fuel, compression.
