If the car ain't a relic then no. Aggressive shifting is not a big issue with car transmissions, they are made to handle the stress. But not improper shifting of course. Simply said, don't do it if you don't know how to.

@Xulfiqar @capsat
Your views regarding aggressive shifting or Shifting at higher RPM as 2 different opinions are coming above in response to query raised so please guide the readers.

Old school myth of shifting gears at 2K in M/T (Except gear#1 with flexibility to stretch it to 3K).

Another old myth is to change/ shift gear at higher RPM like at 3K during Winter seasons(Gear#1 at 3.5K) so is there role of ambient temperature in this mechanism.

Will aggressive shifting heats up the engine quickly?

[anc]

engine revving at higher rpm's will generate more heat, but I doubt it will 3k rpm will cause damage to engine.

with paramount excitement while driving a manual car. KE30 4 speed, without RPM meter sometimes i forget to shift down and keep on throttling in joy. Temp Gauge remain static

it is over 3 decades approx, before getting hold of a manual car i.e KE30 in late 2018

Screw clamps are bad, find the original spring clamps and remove each hose one by one and check for inner liner fracture at edge

Asalamu alaikum I hope you are fine.

I am getting P2109 error whenever I connect scanner to my car. Using recommended oil. STFT LTFT values are normal, vehicle and calculate load at idle without ac is below 25. Everything is fine still getting this error. Please guide what to do.

Engine rpm is not a fixed number on all engines, some engines have to rev to make some power, while some engines are low revving

E.g. imagine engine with 2800 rpm redline

You have an accelerator pedal sensor problem, its probably damaged. Replace the sensor.

Did someone washed the throttle body?

Is he right?
How to properly replace fluid

[pwuser161228146379]

Yes when I bought the car I cleaned throttle body at home without opening it and cleaned MAP sensor too. After that I have done throttle calibration several times but still getting this error.

[Hassan1991]

Something went bad with it.

[pwuser161228146379]

So what should I do now? Replace accelerator padel sensor? Or replace throttle body?

[tmuzammil05]

Got some waste cleaned from fuel lining. The person who cleaned the tank was inexperienced and reversed the pipes while fitting them back. It resulted in ECU damage which I got changed.

[Xulfiqar]

This code is the app sensor, not the TB, did someone do any detailing work in the car or was it water damaged anytime in the past?

[pwuser161228146379]

It is imported car Vitz it was not water damaged and I think the dealer from which I bought he has done detailing before selling car. Three of my friends are also facing this issue in their Vitz 2015 my car is 2017 model. I think it is manufacturing fault in Vitz.

By lining you mean lines?

Because lining is a different thing altogether.

I have a Honda City 2014.
There is a leak in the valve cover gasket.
And oil is dripping on the floor.
I want to replace the gasket.
There is liquid Gasket mentioned in workshop manual which is to be applied on cam chain case contact areas.
Is it normal silicon gasket maker?

[Xulfiqar]

It is oxime cured silicone sealant.

Buy some mega gray or ultra gray and use that.
