'02 HD

Posted May 10, 2003

Still trying to find the source of my vibration in the accelerator pedal at highway speeds.

I started looking close to the throttle cable on the throttle-body end last night and noticed Delphi Part # 1997279 (Fuel Tank Evaporator Control) has a vibration at idle and rises as the rpms increase.

It has a rubber washer/bushing where it attaches to the manifold so I was wondering if this is to isolate the vibe or is the part defective? I am going to test drive the truck this morning to see if I still have the vibe.

Any techs out there that have seen this problem with the 2500HD 6.0L?

???

So pretty consistent with everyone else’s experience- you can do NOTHING.. worthless emails. Sure glad i have 4 GM cars on our family cuz now its clear you dont care.. Sad and pathetic.
