Car Jerking on throttle

[Replay]

Need your help sifu's,

I just got back home and when driving home my car was very jerky when on throttle, just mild throttle only it will jerk, when it starts to jerk, the engine doesnt sound like its firing properly and there is no power to the wheel. the more i depress the throttle, the more the engine jerks...any idea whats wrong???

You lose alot of power, right? I think your spark plugs are burnt, need a new set of replacement.

either ur spark plug already kong... need to upgrade and change ur spark plug(suggestion.. get irridium plugs) OR.. ur petrol tank indicator spoilt and no petrol is reaching to ur engine..

If idling also got jerk, then maybe mis-firing.

Check every spark plug,
Check every plug cable,
Check RPM.

I experience that twice with different cars, idling also got abit jerk, jerk more when throttle, one time is due to faulty spark plug, another time is due to 1 faulty plug cable.

urm..... ur car is a manual or auto... if its an auto.. there is a possibility that your gearbox something wrong... coz i went thru that before on a auto gearbox.... causing ur car to jerk in the beginining.. and like got no power.... feels like as though spark plugs got some prob... but then as time pass by..... every now and then the gear tak masuk....
so... it could be a whole load of possibilities... give it more time to show its true nature first ler...

If it's an older car, also remember to check your fuel filter. People almost never bother to change this.

Thanks for all your feedback guys,

I brought my car to my mech today, he fired up the engine, listened to it for a bit, pressed de throttle for a bit and said it was my plugs. Poped open de bonnet and checked out the plugs, true enough there was some water and it was shorting out the plugs...dem it...like that also can...

never going to send my car to car wash and ask em to wash my engine

lucky i brought it to my usual mech to check out..i reckon other mechs may just get me to fork out $$ for a new set of plugs..

can now go back to full boost with jerkiness.....phew.... :)

Yo bro .. May i ask, coz im driving a Saga, so the fuel filter is at the firewall slightly lower .. I believe it can be easily DIY-ed right ? Just have to loosen the bracket n pull out the hose , pull out the fuel filter n just fix it n put it back in ..?

Is that the right way to replace it ? Or its better to send to the shop ..?

Not sure where it is on the Saga, but yes, that is where it is with the more recent Protons.

You can do it yourself, as it's quite straightforward. All you'll need is a wrench to undo the nuts. Make sure you get the right size filter, as there several sizes for Mitsubishi/Proton, else you'll have difficulty fitting the bracket back onto the firewall.
