Hello All,

The S seems to have developed a strange vibration around 3-4k rpm, it will then smooth out then when vtec kicks in it feels hesitant and is not as smooth as was a few weeks ago,


the vibration feels the same as a wheel that is not balanced correctly,(shakes the cabin)but then smooths out????

and in vtec, the best way I can describe it is, it feels like fuel starvation????? (but no vibration)

The car has a de-cat, after market exhaust, and a CAI kit, I also fitted new tyres all round (falkens) and changed the oil and filter (castrol edge 5/40)

all this work was carried out a few weeks before JAE and the london tunnel run and the care drove like a dream for the whole 540 miles, so I am struggling to tie the symptoms with any of the above work,

I have checked the oil level, all the wheel nuts and the car nothing is jumping out at me,

PS its a MY01, with 103000 miles,

Any ideas would be a big help, Thank you Mark

 

hi mark,

Does it vibrate the same when stationary or only when moving?

Hi Zud,

Only happens when the car is diving under load, and in any gear,

Had a look at some other posts and wondering if it might be an engine / gear box / diff mount

Or mybe the prop shaft???

 

It could be the driveshafts...these symptoms sound similar to what andy2000 experienced ~ 15 months ago...he also had a similar mileage to yours.

Fitting driveshaft spacers would rectify the issue, or swapping the buckets over.

Have a search for driveshafts Mark and see if your symptoms tie up with anyone else's.

 

Thanks Matt,

I have also fitted the HKS lowering springs last week that I picked up at JAE, so was thinking about some spacers anyway, so I will look into that,

I did not mention the springs in the first post as the car had the problem before they were fitted,

 

They wear without the ride height being altered...just as Andy's did

 

How much does hks springs lower by?

 

Bought them second hand, according to the seller 25mm front and 30mm rear

before......




after......

 

Yup I'd say its driveshaft spacers needed mine did the same after I fitted the springs (still haven't got any spacers)
