Capless fuel system whistle
I seem to be getting a whistle and a chirp from the area of my fuel filler neck at throttle tip in. Any ideas? 2016 C7 Z51 1500 miles. Have replaced vapor canister purge valve, and purge solenoid near intake, and checked fuel tank for leaks. No codes have been set. y the way the exhaust system whistles as well in Touring mode.
