since i bought my 98 SE it has vibrated when accelerating from 25 to 30 mph. it doesnt matter what gear but it does it more in 2nd. any easy fixes or is a tranny/cv issue?

 

I've heard it's an injector problem. My car started doing this recently and I'm trying to remedy the problem as well. I just got a new knock sensor and am waiting to install it but I've heard that could be the source as well.

 

just put in knock sensor monday... not it. i thinks its drive train because it a speed issue and not a rpm issue. but the knock sensor is a good buy, night and day diff but not on the vibration

 

What kind of vibration is it? Is it an engine, tranny vibration or more of a chasis/wheels type of stuff?

 

i really dont know. thats what im asking. i can feel it alot in the steering wheel.

 

Try to break it down for us more.

At what speeds does it vibrate/vibrate more
In certain gears?
Only when braking?
only when turning?

Whats your tire pressure?
Have you gotten an alignment recently?
When last were your inner/outer tie rods replaced?

 

somehow I think he's a victim of tire balancing/alignment..

 

I bet you a bad alignment

 

jack up your car and secure it on stands, then turn on your car and put it in D. if your wheels are unbalanced you will be able to see the wheels shaking

 

its got brand new kuhmo ecstas and i got my allianment done and the tireds balence twice after i pu them on and it sitll did it. and as i said befor its in any gear fron about 25 -30 and i feel it through the steering wheel. it did it just as bad now as it did befor i lowered it so i know its not that. i was thinkin maybe c/v's.not sure how to check.

 

the only thinkg i know about checkin c/vs is to listen for poopping when turning and to also just reach under there and feel for slack. no popping out of em....but when i wiggle them theres no slack either. when i turn them there is a little play on the tranny side but not much.

 

check control arm bushings as well? oR wheel bearings?

 

i checkes wheel beringss. i jacked the car up and even tugged on the tire and no play at all. i also cranked the car and eased of the clutch with it in the air. no woble i just dont get what the shake is. i may need rotors but they arent that bad. just alittle shaky under braking

 

if it's just shaky under braking, then it's he rotors

 

I don't know if you have aftermarket wheels, it could be the wheels don't fit correctly. Might be right bolt pattern, but you could need to add concentric rings under the wheels to fill any gaps between the wheel and the axle. that's the problem I had, and the rings made a huge difference. smooth as Crisco on a slip'n'slide now.
