Recently I'm hearing a slight 'clack' when operating the gas pedal. I don't know if it's mechanical as I don't feel any associated physical vibration. It's almost like an electronic relay but, loud enough for this Tinnitus person to hear. Clacks once when pressing on the gas, and Clacks once more when letting my foot off the gas. No error codes or indicators. Operation seems otherwise normal. Because I'm hearing impaired, the clack seems to come from below and to the left of the driver's seat. Any ideas? Thank you
