    missfire

    Hello trusted forum friends, i have some kind of missfire, when boosting 1,4-1,5 the car goes brrrrrp brrrrrrp, seems the sparks are not good enough.
    Any idea??

    its not the n75 valve, its new. (tt 225hp) no boost leak, all new samcos.
    Can anyone tell me where and what i should get as a spark booster (msd??) or something like that.

      Check your leads particuarly the one going to the dizzy mine got trapped between the brake lines and the uprated strut i had fitted, this resulted in bad missfires as soon as I got positive boost.

          now the problem starts from 1,2-and up comes sometimes and sometimes not. Any ideas?? if i floor it fast then this happens straight away, if i give it nice and smooth then it goes well up to 1,5..
