Hi guys, Was wondering if any of you gurus could help me out with my problem.:hmmmm: I'm currently driving an Wira sedan 1.5 auto, year 2000. When I'm in Neutral(N) d engine rev is @ about 1K which I feel is normal. But when I put it in Drive(D) or Reverse(R), d rev goes below 500. I've tried servicing the TB but d problem still re-occurs constantly. Recently, it has become so bad that the car sometimes even stalls wen I'm reversing my car or accelerate out of a junction. I'm afraid I might get into an accident sooner or later if this keeps on happening. Do any of u sifus have any idea on whats goin on or how 2 remedy it? Pls help.. Btw, the only aftermarket part I've put in is an open type K&N air filter.
