Hello boys and girls.. below behaviour is normal ? constant flacuating from 13.5 to 14.5 like non stop with a bit rough idle, nothing too crazy or worrisome but defintly not "relaxed" idle. same with rpm slight very unnoticable flacuate. 2018 GT premium | very hot weather if it make difference. car is HP tuned for catless and it has double X-Pipe.

I really think its air/fuel sensor.. ?

Don't go by that gauge. It is highly inaccurate. Mine bounces like crazy when driving, but doesn't reflect actual numbers. Look at the screen with the actual physical numbers.
What is it showing at idle on that?

The rpms could possibly be a spark plug issue.
