hi eveyone, new to this site so bare with me, i've been driving a very clean white sti2 for 5 years, brilliant car had very little trouble until last year, the problem i'm havin is when you drive normally its fine but when accelerating under boost it seems to pull in spurts (only way i can describe it) this only started when the weather got warm and it stopped doing it when the weather got cooler, the same this year?? changed coilpacks new plugs and tried a new maf but no improvement, very annoying as the problem went away when the weather got cooler. any help or ideas would be brilliant as this is driving me mad.
