I have 105K miles on my car and it has:
chip
3" TB exhaust
and lowered with coilovers.
I recently went back from Polyerthene mounts to stock type because due to a vibration i was getting under WOT. But even with stock mounts I get the same vibration.
I have an engine code for a boost leak (boos control range not reached code) and slow resonse O2 sensor.
I am wondering what could be causing this vibration?

Re: Vibration under WOT (sle39lvr)

mine does this on a WOT pull, come to actually find out its the clutch slipping on the flywheel creating a small harmonic vibrations. In 4th she will slip and jump rpms

make sure your 3" exhaust isn't hitting anything under a load?
I.E. the downpipe. also the rear axle is a tight spot. just a suggestion. is this vibration audible? or you can only feel it?

Ya you can only feel it..
It feels like it's scrictly coming from the engine or the transmission.

Vibration under WOT that feels like a rumble/wobble is usually a CV joint.

sounds like you're makin too much power

Back it down about 12 psi and you should be good to go http://****************.com/smile/emthup.gif

I've never seen a worn/slipping clutch cause vibration under WOT.
