Ok where to start,i have a 98 TA with a headers, intake, TB,and cam. The car has been HP tuned,and i am still having troubles, like if i start the car and don't let it warm up long enough it will try to cut off. And if i am out driving and lets say i need to stop and put the car into reverse fast, the car will almost die! O i also have a 3500 stall. And around 50 mph when i am just costing along the car will jerk. Sorry so long thanks for the help.
