Been having a a juddering for a second or two under heavy throttle, ease off and ok will judder with .5 bar but will go to 1 bar
it happens at various speeds and revs.
When its cold it dosn't happen straight away had full boost and no juddering and car went like a rocket
after a couple of miles started to happen when warmed up.
Waiting to get a pressure test for leaks, checked for visable and tightend hoses.
Changed vac line, diverter valve, put new air mass sensor, coolant temp sender,fuel filter
nothing when scanned.
Think of getting a set of coils? ignition control module?
car seems fine when cold? car 1.8 tqs remapped
Ideas as to why fine cold ?
thanks
