vibrating to death

I have a 98 and when i give it gas it has a bad vibration and not its not the shaking of the steering wheel because of the oversize tires but when i take my foot off of the gas it stops??

 

fuel pump may be on its way out. whens the last time the fuel filter was changed?

 

never lol

 

a little bit but not bad enough to be making it vibrate that bad

 

change the fuel filter,and let us know what its doing afterwards.

 

if it has anything to do with poor acceleration....clean the maf sensor and also the throttle boy.....and iac may be next.

 

na its not in the floor and the motor isnot missing its in the whole truck all the joints are good and everything i have took all the brakes apart cleaned the mud out and cleamed the undercarage very well and it seemed to help quite a bit but still vibrating quite a bit.

 

Or perhaps a bad motor/tranny mount.

 

I've got the same issue. I've only got 700miles on my V6 AC. When I'm going around 55 and I accelerate slightly, everything vibrates (kinda of a deep waaaaa waaaaaa waaaaaaa waaaaaaa). It only happens during acceleration from 55 to 70. Started about 200miles ago. It's not vibrating like crazy but enough to notice and bug me.

I'll get it checked out when I take it in for the first service. It happens every time I hit that speed so hopefully they will be able to figure it out.

I'll report back to this post later.

Cheers.

 

U joint!! Cant see it until you take it apart...
