newby question regards judder in low gear

[netmgr]

Ive been reading through the FAQ and it seems to be a common fault for a judder in low revs, it happens in mine usually if im stopped in a queue and then set off it can be a bit jumpy for a split second, doesnt always do it and once its done it one doesnt do it again until ive been stopped moving or gone quite slow then set off again and when i say set off i mean normal town traffic, not flooring it

Im going to do some more tests and see if its an engine misfire or clutch, a the moment it seems to be clutch, ie when im stopped and rev it it seems to be a smooth rev band, only seems to occur when driving off.

 does this sound familiar to you guys?

the car is an early 1993 japan import so im thinking its the start of the production run.  were there ecu issues? i notice from the faq there seems to be, however that states the issues is when letting off the throttle, mine seems to be the opposite - however they may be related

looking for any suggestions you may have as to how your early wrx runs

cheers

Its very normal caused by the flywheel wearing uneven give it a few flying starts without slipping the clutch other than that wait till you replace the clutch and get flywheel skimmed i wouldnt worry about it.

The only clutch judder i used to have, was from cold at the start of a journey.. this happened not so much in my classic, but alot in the bugeye..

Me too I'm afraid - seems to be a curse on the old bugeye.

Get your flywheel skimmed and that should sort it.

thanks for all your posts, however im not entirely convinced

I wouldnt say that the judder occurs when cold, quite the opposite

I need to do more testing, but its clear that some juddering is to be expected when cold

Ill see what shes like on the drive home tonight, see if it is clutch judder or a misfire

If you think its a misfire coilpacks are the usual culprits on early models but from how you describe it it sounds like clutch judder give it some hard launches and test the clutch, coilpacks are more likely to break down at high boost.coilpacks can be inspected by peeling back the rubber and looking for cracks in the plastic.
