met up with a couple of friends...ended up doing a lil racing...we leave everything is good...slight KR nothing huge..At the top of second gear it feels like it hit a wall and slowed WAAAYYY down...still drives normal, has a slight tick but that has always been there.. something is not right. All numbers on scanmaster are good but def. can tell the car isnt where its supposed to be. any ideas why the car would just quit like that? mods in sig. engine is new...
