    Hi fellas

    My car is a late euro F113b no lamda

    Had a great day out with my car club at Donington circuit yesterday watching FIA GT1 racing. We parked in the centre of the circuit and had to pass through a tunnel. I blipped the throttle to hear the engine and each time I heard a "hiss" ? Like an air induction noise. This is new.
    My tech has just diagnosed a faulty ignition amplifier as my car has been running poorly-after poor maintenance from my previous garage. It has just had replacement fuel regulators and banks balanced and mixtures sorted out. Now running better but still a little "jerky" at low revs and well underpowered. Hopefully the new amplifier will sort the poor running however I am concerned about this new nose??

    Any ideas where to look first??

    TIA

    All the intake system pipes are fine?
    It sound like a small amount of air being sucked....

    Tip: ask someone else to hit the throttle and liste yourself in the back ....
