    Hi everyone

    I have been trying to find the cause for this problem for a while now, as its random
    Sometimes at first gear there is no power i press on the fuel pedal till the end but the car increase power slowly, sometimes while driving on the 3th or 4th gear

    But recently its started losing power while driveing the car kind of loss power for few sec then it speed up again

    Or when i reach 3k rpm the car kinda feel like it reached its limited can't speed up anymore
    the engine started making too much noise but if i switch the gear up it continue fine until 3k rpm again

    There is nothing in the scanner no fault at all

    The thing i replaced / adjusted in the past 2-3 months:
    - PCV valve
    - Battery
    - Alternator regulator
    - Hydraulic pusher
    - Camshaft adjuster
    - Poly v-belt
    - Fuel Pump the whole thing
    - Adjusted chain belt (Crankshaft)
    - Spark plug
    - checked air filter
    - Cleaned air sensor just incase
    - it used to release white smoke but no it stopped
    - Catalyst converter they told me it has been removed (But am going to take a look at it tomorrow to make sure

    Checked engine numbers while idle with scanned everything is the same like in haynespro

    - The RPM when i start the car goes up to 1.1k then goes down to 680 slowly
    - Cracnkshaft sensor works fine

    Out of ideals and money lol

    Check for a blocked catalytic converter, I do a swift check by taking the lambda sensor out and see if the power is restored. Also peer into the rear silencer, looking for any debris.

    Why don't you take it to Kwik-Fit?
