768 Views 1 Reply 2 Participants Last post by  Kyrocks
Hey all, wondering if anyone elses truck does this, when I left off the throttle and the engine is coming back down towards idle, I can hear the CP3 making a "clack clack clack" sound about 10 times around 1200-1000 rpm. Truck runs good and strong, no stuttering, just that noise when its coming back toward idle. Any ideas?
