Misfire check engine

[Ali Alani]

i have problim with my 2011 tahoe i had the check engine on with a misfire code I changed all the plugs and the wires and its still on I think the problem with 4 cylinder
The car has 179 kilometres on it am not sure if that problem will br coverd under the manufacture warranty
If not how do I fix it with out spending huge amount ??

What exactly was the code that you had? Was it the only code or did you have others?

Is it running poorly or did that code pop up with no change in drivability?
