    Hi Pakwheelers,

    When the car shift to 3rd gear it drop the rpm from 2.3 to 1 and if i push the race the engine start knocking.

    Please advise what will be the possible reason for this.

    Fuel Filter - Fuel Injector or some thing else.

    you can see all your issues if you use a good scan tool to check your car, knock is caused by

    1 - lean burn

    this can be from a clogged injector, leaking intake manifold or even bad valves in some cases.

    2 - carbon build up

    this can be from the engine running dead cold all the time and eventually building up cakes of hard coke in the combustion chamber - these then glow hot and cause knock.

    3 - bad timing control

    self explanatory.


    SO - all in all - its not a simple answer of "yeh kardo set hojaega"
