hi, storeberry (storeberry)
, i had tried many way still no much different. i step on acceleration no acess 2000 rpm i alway retain at below 90km went on expressway , way go down slop i never step , and jz let it roll down .but not much different if i step hard on the accelerate as what you said , i go can go up to 297 or 300km only that why i keep looking for the solution to solve and find out what going wrong. my vios got power to move on traffic light , i can rech 80km 0n 5 sec . only the problem is i realize if i normal drive to test for checking the fuel consumption , then i relize why mine so high consumption ..HEADACH. your also auto but better than mine can go up too 500 plus .
