Hello there! I am in desperate need of help! I have an 03 Honda and I am experiencing shaking/vibration around 48-55mph! I have replaced all the motor mounts, tire's have been replaced, balanced and aligned, changed the axels, new brakes and rowdier's! We also got the oxygen sensor's and spark plugs changed!

NO ONE can seem to tell me what it wrong and want to keep "trying" things at the expense of MY pocketbook! I don't know if it is worth taking to Honda paying them $100 to look at it and tell me what everyone else has told me!

 

What rpm range is this happening? Do you have a 4 or 6 cylinder accord? Automatic or manual transmission?

 

Ummm I don't know I never really looked at that, it is a four cylinder and automatic

 

Does your check engine light turn on while driving, or the D4 light flash?

I wonder if your EGR ports need cleaning? The car would stumble or shudder at ~2000 rpm. There are write-ups for the 90-97 4 cylinder accords and the 98-02 accords. I am not sure how to clean the 03+ accords, or if that is even a common problem.

 

No it doesn't the only light that has popped up was the mant requi light when you start it

 

Is the vibration felt in the steering wheel or where?

 

The steering wheel did shake but stopped after they replaced a tire that had a bad belt in it, not the vibration is coming from the front of the car

 

I've heard of vibrations being caused by compliance bushings (large rubber bushings on the front lower control arms). It wouldn't hurt to check them out, to see what they look like. You can see them pretty easy, in front of the front tires, where the control arm attaches to the frame. With all the stuff you replaced to this point, I think I would look closely at suspension parts. Seems they would have checked all that before they did an alignment, but maybe not.
