Question about Hyundai Sonata
What year is the car? If 2011 or later you have a GDI engine. Beautiful new engine design with a very high pressure fuel pump to boost the injectors to about 1600 psi of fuel pressure. Sits right under the main plastic engine cover. Should be a very audible clacking sound when cold starting that reduces to a clicking sound fully warm.
Enjoy the nearly 40 mpg (thanks to that GDI motor), and be sure to say YES when your dealer recommends a fuel induction service every 30,000 miles. BTW.. don\'t blame them, blame the EPA for having crazy emission standards for cars when a diesel truck can spew black sooty smoke into the air enough to choke you, and nothing is done. GDI is great, but prone to carbon buildup by design, and this condition is increased 10 fold by the ethanol in modern gasoline.
