hey guys, im new to the group and wanted to pick some of your well informed minds,
i have a 2011 mustang gt, all maintenance always done on time. stock other than mufflers. on a cold start (intermittently) im getting a hiccup, and then a "clunk" sound. spark plugs are NGK iridium and done not that long ago , synthetic oil changes every 4,000km, and premium gas only at shell, its driven very little (2,000km a year) and stored in the winter. not sure what to do, i booked diag time at my local ford dealer but im not always able to replicate it. once it warms up it idles fine. no codes
current odometer reading 91,500km
heres a vid of what happens
