Also a good idea to see if any dust has bypassed the air filter.. clean
screen and housing if this is case.
Then change the fuel filter.
That car is not made for premium... wean it off of it. And quit falling for
marketing crap. That stuff is for performance and supercharged engines.
Use popular brand from high volume stations
