Snce getting my lastest VR a 96 obd2,ive been donig various maintence bits on it,yesterday got round to cleaning the throttle body.All went fine and looks spotless now,Before starting the car after refitting throttle i had disconnected the batt and 'reset' the throtte alignment (as per the hall sender cleaning guide on here). Started the car and revs went up to 2k then dropped to 1500 where it stays now when cold.Idle eventually settles down to normal when warm but does take a while to settle back down when driving-e,.g if stopping at a junction-will stick at 1500 then slowly drop to normal.
