1998 2500HD 6.5 Detroit TD
Hello everyone. Hope all of you are well during these times. I have a concern regarding my 1998 6.5 Detroit. Although very infrequent, the truck does a strange hiccup when idiling, almost as if I’m taping the peddle with my foot to imitate a lope. My thoughts are either injectors or a throttle issue. If anyone has any ideas or has experienced similar issues, I’d love to hear how you solved the issue as I am prepping the old girl for a 3200km round trip up north. Thank you in advance for any and all advice!
