Knocking problm in corolla GLI 2010

[hasankhurshid29]

Just met someone at mechanic who said how you can compare cars of Pakistan with other countries.

He was saying is the health of a Pakistani same as American and is the thinking style is same as American.

So how we can follow the practices of outside our country?

i have customers who get their 400k+ honda city's, toyota corollas and many other 400k+ maintained from us. Original engines and transmissions!

Noted sir, could you kindly guide me on what steps I should take to end this issue?

Update:
I have started to shift gears at 3000rpms, but still whenever there is a gear change there is a slight hesitation then it knocks and after a jerk it starts moving.

[rajaatta]

Where are you located

[Hassan1991]

Any hesitation on Wide open throttle?

[pwuser165176643628]

Islamabad

[pwuser165176643628]

Sometimes it will knock what ever I do (mostly when it is at operating temperature) other times it won't knock even if I shift at 2200rpm(mostly at the starting of the day)

Knock/hesitation

[Hassan1991]

Take it to @rajaatta. Let some professional drive it first. And do update the thread afterwards.

[Xulfiqar]

You have knock and hesitation together?

[pwuser165176643628]

Yes, when there is lack of power the engine become rattly and car doesn't pick for a second or two after each gear change. There was serious knocking in which loud pinging was heard before tuning but that is solved now. Only hesitation and pinging remain(I tuned it when u said to check MAF sensor a month before)

[dms664]

When was the transmission fluid changed? I hope and pray it was changed.

[pwuser165176643628]

Around 10 months ago, but I do suspect that the oil was copy as he was very sus

[dms664]

Manual transmission fluid is not that expensive and why you didn't get it done from the dealership?

[Xulfiqar]

I think his car is facing something else,
It needs a scan tool to enable TE2 mode of toyota and then log the knock sensor counter to see whats up

Update#2
So upon many people saying to change gears late I have started shifting at 3000rpm. But when ever I accelerate or change a gear(whenever I demand power from the car) it starts knocking and doesn't pick up. I'm afraid of revving past 4000rpm as I fear something might break as the car becomes generally noisy and doesn't like revs.

[Xulfiqar]

You need to get the car to a real proper workshop, not parts changers.

You probably have a multitude of symptoms acting together.

[pwuser165176643628]

In your experience what has been the most common issue at this mileage on this specific model of Corolla. I don't want to have the engine opened by an in experienced mechanics as that creates more issues than it solves

[ifadey]

I suggest you visit @rajaatta or @dani_kk. Both are based in Islamabad. They will help diagnose it properly.
