my infinity 2010 does same thing ……rough on start up
We can’t see what this “same thing” is…could you be more specific?
Are there any other symptoms? (such as every start vs intermittent vs cold starts vs hot starts) Could you provide any more information about your car (such as mileage) and what (if anything) you have done to try and remedy the situation? Is the Check Engine Light on and if it is do you know what the codes are (note, most auto parts stores like Auto Zone and Advanced Auto will read the codes for you for free, post them here)
