Vitz , spluttering when reving..

[D33ZZ]

Hi guys having some issues with the car ,

Turn the car , when cold takes few turns to get the car running when so it idles fine
When slowly revving the car its revs smoothly
When pushing the pedal right down or fast or down and up constantly , its starts to choke , splutter , whole car shaking then slowly revs back to normal or some times dies out . I have to quickly release the pedal and slowly rev which goes to normal way of revving.

So if you can imagine driving like this its much worse on a stop sign or traffic lights from 1st to 4th like that.

Have replaced the sparks , cleaned maf check all vacuum hoses ,fuel injector cleaner (Same issue), which the old ones had black stuff on it (Sparks), Oil and filter is way over due as like the rest of the stuff to be serviced also.

I have a fcon mini installed , No engine light came up which im shocked about. Have no done a scan for any codes yet.

check your fuel supply or even go do a dyno of it,sound like mine one when the supercharger kick it,sound like need a re-tune,hope this help you.
