I was driving down the road the other night...Everything was fine untill i decided to give it some gas...It felt like the car was shuddering...But i dont think its my engine because it idles great and SOUNDS smooth when driving and accelerating...I feel it beneath my feet. I guess it feels like my tire is going flat..I was thinking it could be that the weights might have fallen off my wheel, and its unbalanced...But it doesnt do it untill i give the car gas...Please feel free to give me your opinions on this..All help is appreciated! thanks!

 

could be the ATTS, it's just in front of the firewall on the drivers side

 

Wouldnt the ATTS light come on?

 

not neccesarily, something in the unit coule be vibrating, even though it is functioning properly

 

Anything specific i should look for?

 

i don't know, i don't have an SH, but sense your a feeling vibration in the same area as the ATTS unit, i thought it might be a good guess

 

ok, appreciate it!

 

My friend's Civic SI had the same problem.
It was because he had a bad axel.

 

I have the same problem! and i dont think its atts because i have a 94 si.....and it only happens every once i a while...i thought it was my tires too because i had a tire that would get chronically low every 3 weeks or so...but it only does it under accelleration! and it doesnt do it everytime! i only notice it at highway speeds, and only about id say 2 or 3 times out of 10

 

Finally! Someone with the same problem! And it does it only some of the time too..I looked under the car the other day, and i have a ripped CV boot on the driver side. Could that be part of the problem??

 

maybe.. my brother's did something similiar when he first got it.. i forget now if it was with the CV or the axel somehow slid out just a little

 

Your CV joint is finished.. new driveshaft time.

 

couldn't he just replace the boot??

I guess it's t late because it's vibrating eh?

 

Well damn!
I guess im gonna go get the wheels rebalanced and see if that fixes it...If not then i will replace both axles...Anbody know the cost of axles...i will do the labor myself.

 

Just have your axles rebuilt

 

well i just asked a buddy of mine, and he said it was the cv joint(s). glad to have found out what it is bud mad that i have to spend money to fix, instead of modify!!!
