Throttle noise?
 

I just traded my ford for a 1998 chev 6.5 3500 (so happy) only issue i am having which isnt even an issue is a noise that i am hearing...
When i put my foot on the gas pedal i am hearing a fast ticking noise, as soon as i release my foot its gone, no matter what gear or what speed... can any one diagnose or help me out
thanks
