After the new timing kit and re setting to specs, i had the TS 2.6 auto out on the Monash and noticed a slight shudder at around 100kph.

It can't be related to wheel balance as it disappears when you take the foot off.

It only does it under load at 100. It may be related to timing or tuning ......anyone had a simmilar problem crop up? If so please post!!

Ta:cool: :D

Oh that will be anoying to fix.

Unfortunatly it can be so many things that without driving the car ourselves, it impossible to diagnose.

Take it to a mechanic or an ultratune and ask them to have a look.

check the TPS setting and air flow meter

will be either an engine mount gone, or one of your cv's. i have this problem. replaced the main engine mount and it solved half the problem but i have another engine mount that is partly stuffed (as a result of the main one being so bad). the guy at the local suspension place said e has also had a few fwd cars have it happen due to cv's getting flogged out a bit. but i would check your engine mounts first.

Yes I have changed the front engine mount but it still does it! CVs were new 45,000k ago!
Maybe rear engine mount or TPS!

Moz:confused:

i know in my case te rear engine mount is gone and the front has a small crack in it. the rear engine mount is onlt about $50 as it is just the insert rather than the whole thing.

might be worth jacking the car up and having a look
