Okay so every time im driving 55mph or higher for a constant amount of time ( like on the freeway ) my car runs extremely rich. the car starts sputtering and on my afc neo it reads In2 0.0000 under the senser check mode. And to stop it from doing that I have to push the clutch down for about 5-7 sec and let it idle then its fine. but about a minute later it dose the same thing. so I have to drive 50mph so it woldnt do that. Went to darkside and drew did a street tune. and he said that the only way to stop it from doing that is to get a DSM Link. I have a walbro 255lph. so is there any way i can stop it from doing this without getting a DSM Link. Oh its a 95 gst

Thanks Jeff
