Idle Rev Problem......

[Kevin84]

Hey guys...I have a R34 GT(RB25DE). Recently I got the idle rev not stable and usually higher than normal. For example...I drove as usual and I approaching to the red light....so I release the acceration pedal...the rev drops down....when it hit about 1000rpm...It will bounce back(not all the time but most likely) to about 1300rpm....usually just bounce once but it make take more..... It's really annoying and frustrating coz I feel sad if I see the rev bounces....Any one any suggestion will be great appreciated....

it's been covered before mate. some simple answers to questions will help others narrow it down to.

have you serviced it recently? or is it due for one? if you haven't then maybe that should be the first thing to do before asking around what the diagnosis is. you'd be surprised how often a fresh change of oil, filters, sparks will solve many problems.
