has anyone had a problem with a gtb automatic legacy with this dreaded hesitation on it i have a 94 legacy & it has an annoying intermittent fault in that when you are accelerating it feels as if no fuel or spark is happening & you can have your foot to the floor but it only goes about 20mph??then all of a sudden you get the power back & it can be fine for weeks & then it starts playing up again have been using a mixture of 97 super & 95 reg unleaded this doesnot appear to make any difference. i have read that this hesitation can be a common prob with turbo scoobys?any help would be appreciated
