I own 2015 c7stingray misfires but will not give a code. Should I start by changing spark plugs
Is the check engine light on ? Does the check engine light work?
If it truly is a misfire and you do not have the tools ability to diagnose it, changing the plugs would be the first thing to try other than bringing it to a shop.
You sure it is a misfire and not the cylinder deactivation doing its job?
