im having trouble with the throttle opening when changing up gears, revs increase when clutch is depressed and are slow to come back down when off throttle.
cleaned throttle body - no change
changed throttle body - minor change
no fault codes or errors when doing live readings with tech 2.
really bugging me as its hard to drive in traffic.
could it be the pedal stepper motor? all parts are from a Vectra B.
any help would be great.
