hey guys,

i have a problem where my car is literally shakes like hell when i dont step on the gas.it happened a couple of days ago and its getting me worried. It seems like the shaking came from the engine itself but i cant confirm whether or not its a transmission problem or a spark plug problem or is it something else going on inside the engine itself. The engine itself is shaking and choking like its going to die on me. Does anyone have encountered this sort of problem before and what are your countermeasures? Any sifu please help especially myvi sifus..i'm driving a myvi 2006 auto.

Thanks.

bro dares,

is it? i'm using denso iridium spark plugs..will try to open up the spark plugs and see if its OK.

bro Shawnzz,

i've opened up the air filter and see the throttle body..seems ok i think but anyhow will try to open up again.

Update:-

now every gear is shaking and choking...gear 1,2,D,N,R and even P..i think i dont have much time left with this car..please do help me..

I see...d mechanic suggested me to change the fuel pump and i've changed to a newer one..but i think that is not the problem..will try changing to a newer spark plugs tomorrow.


apparently, the idling is OK..it stays at 800rpm during the shaking. but will try to visit the mechanic tomorrow morning.

oh,ok bro..do you guys know any good mechanic around sunway which has the myvi module? because my dad's mechanic doesnthave the myvi module..he told me to go to SA to check the ECU.

ya..its the same mechanic..sigh..after changing d fuel pump, and the problem still persist,he told me to go to SA to check on the ECU. Will have it sent to perodua glenmarie to scan the ECU tomorrow morning.

I've changed my mounting to a newer one a couple of months back.I dont think its d mounting problem.

guys, already changed to a regular spark plug..will see the condition of the car for a couple of days..perodua glenmarie told me that they could not find any problem with the car..they've checked the ECU and spark plugs but everything is normal..i'm puzzled..

really aa?i changed to a regular spark plugs from SA..cost me rm30 woo..they say..its original and its NGK..

bro, is this to reset the ECU?

I see,but the Perodua Technician informed me that there is nothing wrong with the ECU..until today..no shaking at all..does this mean that the spark plug is causing all of this unusual shaking?

guys, this morning, the same poblem happened again..th car feel underpower at all rpm range..idling rpm is almost 500. is there a possibility that one of the piston has gone bust?

guys, i've been thinking, does it have anything to do with the 'tepet' (i don't know how to spell it but often people adjust the tepet)?

does myvi have a wire plug? i thought all myvi uses distributor...

no, i didn't clean the throttle body..but i've open up the air filter and did not found anything unusual on the throttle body.

ok,will try to clean up the throttle body..but out of curiousity, does it have anything to do with the tepet?do the tepet need adjusting?

edit:-

the correct word is engine tappet.

i've sent the car back to perodua and let them drive the car for a few days to determined the real problem..hopefully they will know what's wrong with the car..

but this one..if tekan.only vibrate a little oni..but during idle it gives a knocking sound..i can hear the sound clearly..

ya..sometimes the car is running smoothly..no issues at all..then all of a sudden..the problem starts and then it is ok again. the funny thing is, when i was on my was to SC, the car was shaking the whole journey. right after i enter the SC..all of the shaking is gone..and went for a test drive with the mechanic..the car is OK, no issues at all. *this car is playing games with me*

damn...its quite troublesome to identify the problem if that is the case. and it consumes a lot of our precious time just to identify the problem. but in your case, you have a good mechanic there..i puts in quite an effort to rock your car in such a way just to replicate how the car moves when going over a bump. most of the mechanics i've known will not go to such extent just to find the right problem..hence they opt going for the guessing game.

woo..where r u living?if its near sunway area..then i can oso be a long time customer to your mechanic if that mechanic have that sort of commitment and passion in solving his customer's car problems..anyway,i still didn't hear any news from perodua regarding my car..its been 3days of testing..if they couldn't find the source of the problem,then i give up..sigh..

Guys,after 4days of extensive test drives..they finally concluded that the problem is the car wiring.they changed the ECU, spark plugs,cleaned the throttle body and checked the pistons but couldn't find any problem and they told me that their last bet is the wiring of the car..whats the connection between the wiring of thecar and the engine? I just don't get it..my friend told me maybe thereis not enough electricity going to the engine..doesn't make sense to me. But last time, i remembered my dad changed his wiring harness for his benz but forgot why and he also forgot why he changed it. Does anyone have any ideas? It will cost me 700 to change to a whole new wiring system.

they say that its the harness wire..the wiring to the engine...
