Hi guys, Toyota cars are perfect ( some how ). They make u proud in all cars and driving aspects. but sometimes even with advance technologies, the car may bother u and make u unhappy especially when u purchase a car with your favorite features like here for example (manual transmission). since the very beginning of my driving for my corolla 2009 1.6L engine, I noticed a strange bad phenomenon happening when u shift the gear from one to the other. generally,the car produce a violent shake while shifting. It sounds like the car is releasing the pedal and depressing it again simultaneously. you feel like you are pressing the pedal but for part of a second the car doesn't respond.This shaking also happen in a very notable way at high speeds like launching the car(if you wanna race with someone )especially, when the RBM exceeds 5 .This problem reduces the car acceleration as u need to wait for the car to catch its breath in each sift and that become like riding a horse with the movement back and forth due to this shaking. some one told me that it most likely a controlling system for the fuel flowing to the engine. have anybody faced this kind of problem? and if u did, do u know a way of fixing it or even disabling the cause of the shaking stuff? because I started thinking of selling the car if this problem is unsolvable ( Joking ) I hope u understood the issue.
