Knock sensor....located at the backside of engine block. Behind the starter motor, under the intake manifold.Attach to engine block with 2 wire, black and white. Not very easy to change...
why my car in low around 1000rpm not stable and the engine "semput",and at high rpm won't happen like this.i have change plug,but just can hold 2 months only after that start back again,
I have a SMT6 in my N/A Wira tuned during a typical hot Malaysian afternoon. During hot days in the afternoon...the car runs great - engine revs smoothly and car feels torquey...
