[metalrizca]

[skar19]

[Jules]

erhhh change car!...JOKING!

seriously something wrong w ur car....

go send to mechanic-loh

 

[bmwsideways]

For a BMW to have such a low top speed, there is no question here and send your car to any good and reliable + reasonable workshop you know.

 

[jeembo]

...one more thing i noticed that the fuel comsumption is very high...say like RM80 for abt only 300km drive...car has been serviced...i just got this car last month and I'm totally new to this UDM world...

 

[metalrizca]

well bro,
there's many possible causes..

if your engine is lack of power, it could be:

1. incorrect ignition timing..
2. faulty spark plug..
3. fuel injection or carburettor malfunctioning (what bimmer are you use?)
4. brakes binding.. (well, it's make sense)
5. clutch slipping.. (are you using manual or auto?)
6. etcetera..



if you're using manual transmission,
and the car can't go faster than 110km/h,
and the fuel consumption is high..
i guess, more to clutch slipping problem..

send your car to workshop..

If yours is auto, are you aware of the existance of the so called "kickdown switch/button" located under the throttle pedal? For quite sometime when I newly bought the car, I was driving around with top speed around 110km/h also...until I figured this thing out on my own by accident. Just to share my experience if it helps...

 

[masCh]

the kickdown switch is just like dropping gear right? It shouldnt affect top speed, or am I wrong?

 

[metalrizca]

kickdown switch button..?
hmmn..

hoh..?
no, no, no..
do not press that button..
it will detonate explosives that release the roof of your car..
then, eject you out from your car seat..
ha ha ha..

the kickdown switch is just like dropping gear right?

yup..
kickdown switch is kinda to downshifting gear..

His normal reply, dude

Nothing personal

Theres meaning (as always) in his reply

And as i have mentioned, get the car to the mechanic, no way theres any switches or any buttons that can hold your car to 110KMH top speed only.

 

[jeembo]

hi all....thanks for all the output, here are what i have done...

1. changed the spark plug (free) sponsored by my wireman
2. clean the distributor cap...changed the distributor vacuum pipe, found leakage(rm28)
3. changed my exzos (rm320)

later this evening I'll go check my manifold gasket cos been hearing leaking sound.

a bit difference in performance...and i suspect my clutch is slipping too....anybody knows how much it'll cost me to overhaul? is it somewhere around 3K?

Thanks!

 

[Mikeong]

Under power? I'm sure those guys here have tonns of ideas to make your car fly.

 

[jeembo]

alrite now... I would later do the valve adjustment...does anybody know the valve clearance for this?

 

[metalrizca]

valve clearence..?
what type of bimmer engine..?
still dunno what car you drive..



valve clearence (intake and exhaust)

M10 engine
cold - 0.20mm
hot - 0.25mm

M20 engine
cold - 0.25mm
hot - 0.30mm

M30 engine
cold - 0.30mm
hot - 0.35mm

what if the engine has undergone head skimming what is the valve clearence?

dunno..
i'm no specialist..

he he..
we have sifu here..
any sifu can answer the question..?

 

[iCe]

well bro,
there's many possible causes..

if your engine is lack of power, it could be:

5. clutch slipping.. (are you using manual or auto?)




if you're using manual transmission,
and the car can't go faster than 110km/h,
and the fuel consumption is high..
i guess, more to clutch slipping problem..
