i just got a 90 awd turbo. i replaced the plugs,wires,cam sensor,mass air sensor,coil packs,power transistor,fuel filter,and fuel pump, the car idles really ruff and will pulsate at 1/2 throttle. it will do ok at full throttle for about 10 secs. please help

also i have checked for leaks vaccum and boost.and found nothing.and the tach will not go above like 4000 but i can tell the engine is lots higher it bounces around. and the factory boost gauge dosent work either.
