Hello Genesis coupe family! Ive had my 3.8 Rspec for almost 2 years now (in February will be 2 years). A couple of days ago, I got to a stoplight and when came to a stop I noticed that my rpms werent steady and were fluctuating back and forth.. I stepped on the gas pedal to try to make the rpms steady again. The car seemed just fine after that stop. Does anyone know if this is normal to happen on the Genesis coupes? If it is what can be the issue with the car? Ive been keeping with my oil changes, and I put Chevron all the time. I want to figure something out before taking it to the dealer or the car geta worse. Anyone have ideas? They will be greatly appreciate it.
