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

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

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

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

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. :wink:
