I've found that life I needed.. It's HERE!!
actually i think you should check the mass air sensor..
especially the wires for it.
can you ease the rev to max...if you are beeing gentle..and just when the car sits still?

or mentioned before...the spark plugs ,leads or ignition coil,check for resistance in the leads,has the car gotten the spark plugs changed recently or not?

can a fuel pump and fuel regulator cause this problem ? I believe that have a common fault in in tank fuel pumps as my previous st170 has a fault ?

Hi one more question I still can't find the problem think it could be the turbo actuator it is an uprated one would over boosting cause the problem that I have described ?

you will find that if you change the plugs and leads the problem will go away mate
mine went like it a few months ago changed the above all sorted.If your running big power though the normal plugs wont last that long mine is running 350 and got NGK LASER PLATINUM PREMIUM and 8mm high performance ht leads
