Got a problem here, my 95 wrx is stuttering/hesitating when on boost. it only does it when the engines fully up to temp, i don't give it any boost dead cold but I've noticed it runs fine when the needle shows there's some temp but not fully evened out hot, it takes far longer to show temp than it actually should anyway. Ive replaced the coilpacks, crank angle sensor, cleaned the maf, and swapped my ecus around to see if any of them made a difference, but got nothing, it still does it. it seems to be a fairly common problem, so I was hoping someone might be able to point out something!
