Hi people who now. Got an impreza 03 and when I'm driving along say in 3rd or 4th just normally all of a sudden it start juddering. As a guess ide say it was the spark plugs but been told not. Also it's only in the morning once it's warm I don't notice it ( yet) any sensible ideas would be gratefully received. Thanks alot motoring

 

Possibly the maf wants a clean.

 

Temp sensor maybe. I didn't think cleaning mafs actually did anything. Try a diagnostic check .

 

I seem to be going in a different direction but what about the clutch. Can't remember what there called anymore but don't the springs on the clutch over time get knackered and cause juddering. This normally happens in higher gears at first I think .

 

No, juddering from the clutch usually happens as you pull away from stationary.

 

I get juddering when pulling away from stationary. Does this indicate that my clutch is on it's way out?

 

Not necessarily, could just be a build up on the plate/flywheel causing the judder.

Where is the bite point?

Put the car in say fourth gear, handbrake on well and slowly release the clutch, if its going to stall then the clutch is probably OK.
