    hi guys and girls

    sometimes when i dip my clutch at a giveways or t-junction anywhere really the revs fluctuate between 500 rpm and 900rpm its like as if the engine wants to cut off and then it levels off and no problem

    this doesnt happen at every junction and i understand its not the end of the world but hey im a perfectionist unfortunately and want the car 100%

    i have recently remapped the 1.8t replaced temp sensor and thermostat and replaced the ignition amplifier

    what the hell could this be now !! aaaaargh :banghead::blownose:

    Unplug the maf, go for a drive and see if it does it, if it doesn't you need a new maf

    Maf can do all kind of things, poor idle, poor fuel comsumption, poor boost etc How is it running generally? It could just be a case of your throttle body needs a clean
