car judders when going at a steady speed at around 2k rpm

[jason1987]

i thought it might be the cone filter i had but ive got my air box back on now and it still does it, any ideas? feels like a tugging

[Gary406]

get the engine mounts checked out mate ..

[jason1987]

its not a bad juddering, feels like when youre coming to a stop and youre in a too high gear, hard to explain

[craigtd]

what car is it petrol or diesel

[jason1987]

sri turbo petrol

[jason1987]

could it be HT leads?

[craigtd]

ive got the same problem, im going to disconect the lambda sensor as i have high fuel consumpsion aswell and ive been told this could be a faulty sensor

[Gary406]

could be HT leads. whens last time the plugs were changed ?

[jason1987]

changed the plugs fairly recently, looked at the engine in the dark and couldnt see any arcing/sparks, so now sure what it is, it does it when off the accelerator aswell, so dunno if leads would cause that, or wheel balancing? but wheels wouldnt wobble at 30mph and always around 2k rpm

[jason1987]

if its faulty leads or coilpack, itr wouldnt feel jumpy/juddery when on overrun would it? as it does it when i come off the accelerator aswell

[steve_earwig]

What have you checked/changed so far?

[jason1987]

not much, put standard filter and airbox back on as had universal cone filter on before, plugs are new anyway, turned engine on and looked for blue glow from the leads at night but didnt see anything, dunno what else to do

[jason1987]

its prob the cat causing this, gonna be changing it soon

[craigtd]

what makes you think its the cat ?

Mine is doing the same thing!!! Mine is the 2.0l Petrol on an 'S' plate. Would mine have a lambda sensor being non turbo?

Cheers guys, Mike.
