When diagnosing this problem, did you get vibration at and after the particular rev\'s when the car is parked?

Did you get the vibration at 6k plus, while driving? And if so did it go if you were to dip the clutch?

Don\'t know what the result was of this?

Had a similar problem on a gts, 100+ would get vibration which stayed if in gear or not.

Turned out to be one of the propshaft - diff bolts was smaller than the other 3!


Might help

Yes i,ve cured my fault.
Fitted a HKS twin power. All is well know.

[DMDRIFTING]

I had the same problem on my FD tested the Coil pack resistance to find a needed new trailing coil pack!

Fitted and done, but cold weather is causing slight boost creep, and a miss fire occasionally around 6k.

HKS Twin spark Amplifiers are expensive but when I have the money it will go on with a new ecu etc

Glad its sorted fella

this is an old thread
 
anyway, plugs didnt cure the problem..  I\'ve also dismantled and re-assembled the intercooler piping to check for leaks... but there are are mroe vacuum pipes on this thing than a dyson, and i\'ve not braved taking the throttle body off yet and checking under there.. i have a feeling i\'ll be chucking it at hurley engineering in coventry. i\'m betting solenoid as its an intermitent fault..
