hey, okay i have had this problem for about 1year what seems to happen is that in 1st 2nd(especially) and 3rd gear id get like a jutter/shake just before it shifts! If i drive the car hard it doesnt do it only wen i cruise it! I have no idea what it could be? Any ideas plzzz?
Also what i am cruising on the freeway doing about 100km/hr and if i totaly release my foot of the accelerator the revs would drop then go up then drop n go up untill i put my foot back on the accelerator wired HUH? any thoughts would be greatly appreciated cheers

I have the same problem. Car has only done 8000km's and it shakes in 4th and sometimes 3rd under similar conditions. When I reduse speed it shaked and when I accelerate its fine.[confused]

check your coilpacks (ignition coils) and/or spark plugs thats what mine was doing for awhile until i replaced the spark plugs.....after that in about 15,000 more miles it happened again...when i found out my coilpacks were spent

hey thanks for the replies i got my tranny fluid changed about 4months ago and i have done ignition lead change also about 4months ago so i will try the spark plugs!

I was thinking could it been cause i was using 91octane fuel instead of the recommended 95octane! What i noticed is when i used 98octane it runs much better the shakes and jutters arnt as noticable?Ingector cleaner?

Hi, We us 95 octane here in S.A. Oh and its a manual tansmission. I've booked it in, so the dealer can have a look at it, hopefully they will get to the bottom of it.
