97 silverado accelerator vibrates 42-52

[cazman3]

New posting here, I searched through many postings and couldn't find another exactly related to this....

Recently bought a 97 silverado that's giving me a little vibration in the accelerator / gas pedal only between about 42-52mph. It's not during acceleration or during braking. Just when maintaining current speed. (I'm just barely pressing on the gas at that time).

If I speed up or slow down, it's gone. I've seen things about drive trains, greasing up grease points, air filter problems, dirty plugs, etc... But nothing conclusive. Before I go bringing her in for an unecessary tune up or getting the rear end replaced I thought I'd open it up to you guys..

I'm not a wrench, but would love to find a good answer to try myself or give the local wrench some educated pointers..

I'd appreciate an email to [email protected] and a reply to this thread so others can see the response...

THANKS

have you checked the c/k forum??? that might help you a bit more.....this forum is exclusive to new body style (1999+) but with that said, ill still help....
how bad is the vibration???
have you checked the mount for the linkage??? not sure exactly how its set up but there might be like a rubber isolator that is rotted.....good luck

As I posted in an earlier thread... my '02 V6 is doing the same thing. Not necessarily at any given speed. Just when at cruising speeds below 50 I'd say and when I'm barely touching the throttle. I don't know what it is but its annoying and somewhat embarrassing.
