Problem when car start

[Unknown_G7]

Hopefully the problem is not too serious or else

You want to have a bet with me If you are not helping, don't mess around

I am helping by telling u to see a professional mechanic to see what's wrong with your car.

 

With such strange symptoms, u need some professional help. Not diagnos on the forum.

 

U need to spend some $$$ to solve them b4 they become more serious & u might need to scrap your car pretty soon.

maybe he is saying need to have min. rpm 1k above before changing gear....hee...i also not sure...

 

How to change gear at 1k rpm??? Car cannot even move off in 1st gear with only 1k rpm.

 

Looking at his posts, I thing he is trying to make a fool of us. Or he has bought some strange car.

 

Actually, moving off a manual car even with rpm below 1k rpm is no problem, depending on the control of clutch and accelerator.

 

Even changing gears at below 1k rpm also won't kill off the engine that easily, but I'd guess clutch plate will wear out faster than normal cos the trick is using half-clutch technic while accelerating sufficiently to prevent the engine from stalling.

I used to drive a manual b4 & it's not NORMAL to drive or change gears with rpm at 1K or below. The engine idles at abt 900 RPM for christ's sake.

 

U normally rev to abt 2k RPM b4 changing gears. U can do it at less but not for day to day driving.

 

Have u tried to engage 1st gear & slowly release the clutch WITHOUT pressing the accelerator ( idle at 900 RPM). Your engine will for sure.

Exactly why I say his problem is too difficult to b diagnosed here. He needs to see a very good mechanic.

I agree that normal idling rpm should be around 800 ~ 1000. Yes, I normally shift up gear at around 2k rpm.

 

But nevertheless, even at 600 rpm I could still move smoothly without stalling the engine, like I've said, just need to control the clutch and accelerator simultaneously. Been doing that every morning since mine doesn't have auto-choke, so idling when engine first started in the morning is around 600 rpm without much vibration.

 

As for engaging 1st gear without touching the accelerator, I can manage to move the car forward without stalling the engine. Just need to engage the biting point, hold there a while to get the momentum before fully engaging the gear, all the while without touching the accelarator (idling around 900 rpm). Also been doing that every morning due to bad traffic jams in the morning rush hours before the Jurong Island Checkpoint, so I've been using this method to creep forward from a resting position without touching the accelerator.

 

Guess my clutch plate would wear out sooner due to my driving style.

[Pisces69]

Hmmm..... Very strange way to drive every day.

 

What's the point??? Why don't u just rev the engine a bit to get it slightly warmed up then drive off?

 

For the traffic jam part, it is ok, but just for creeping forward s-l-o-w-l-y. When u have to take off from traffic lights, this method will never work.

 

Well, to each his own, I guess.

 

Cheers.

U mention "accelerator". I tot u only use the clutch? Using the accelerator means u rev more than 900 RPM already.

It takes quite a while for the engine to warmed up till rpm is around 800 ~ 1000 rpm. Sometime after 5 minutes of driving then warmed up till 'normal' rpm.

Of course, moving off from traffic light is different, need to drive normally.

That's when idling rpm is around 600 rpm, then need to use accelerator or else engine will stall.

 

But if idling is around 900 rpm, then creeping forward in traffic jams without accelerator still manageable.

[Pisces69]

OK lah. Since your avatar so funny, I won't go further.

 

And also we both "seafood".

Acutally driving a manual car quite fun. For example, in a traffic light (red) where the car infront move forward slightly to fill up the space infront (but still red light), I like to use the clutch only (w/o accelerator) to nudge the car forward with just enough momentum that it stops without me having to press the brakes. Train my judgement this way.

 

Also when stopping at a slope, I can prevent the car from sliding backward by playing with the clutch and accelerator. Try to control the car stationary by using clutch and accelerator only. Of course, this I minimise as its quite taxing on the clutch plate.

Thats very possible. In my previous car it goes up to 10kms on first 21/22 on second and about 35 on third. All this without using the accelerator, but playing with the clutch biting point and slowly releasing it and when the car fails to acclerate anymore repeat the process and upshift again :)

[Octopus]

Wow, you're good. I haven't tried shifting from 1st gear to 2nd gear or higher gear without touching the accelerator. Perhaps I should try that sometimes.

[Pisces69]

I used to drive a manual long ago when only towkays drove auto cars & had a driver summore.

 

Since I switched to autos, no looking back as the drive becoms so much more relaxed.

 

One of the reasons i switched was cos when i went out drinking & got pissed, i forgot to change gears many times.

 

Now i so used to auto, don't think i'll ever buy a manual again.

 

No offence to all driving manuals, but just my personal choice here.
