Because like you say, they already change almost everything......

if it really was wiring issue, the OBD-II scanner in the service center would have picked it up. (duh)

another cheap solution might be grounding.. just fyi..myvi has very poor grounding, even brand new myvi, after installing quality voltage stabilizer and grounding kit can see consistent gains on dyno.

Problem is only at certain times, the problem surface. When hook up and running fine, cannot detect.....

i thought TS left the car with perodua few days? hehehe.

ya, i left it with perodua from thursday till now..after several days, they called me and told me that the expect 2 issues on the car which are the ECU and the wiring harness.but then i dont understand why is the wiring harness of the engine is capable of making my car shaking like its going to die..fo example..its like you're gasping for air and its like you're going to die..that is the exact situation i'm having when my car shake and choked for air during idling.

If SC with all equipment cannot detect the problem, then finish loh.....

hoh,thanks for the links!..its very useful.

yup,already checked.no engine or warning display.

my car is completely stock except for my air filter, air intake and my spark plugs which is using denso iridium IK20 in which it is recommended my SC itself as this type f spark plugs will last longer and more efficient than regular spark plugs.

hey guys,just got the car back..the SC changed the harness wiring and they changed the spark plugs for free..its the same spark plugs that i'm using which is denso irridium..dunno why they gave me free of charge..

Wire harness also, probably scare you complain to media, wire harness also need to change then spoil reputation........ha! ha!
Anyway, check and see if the problem still arises. If not, then congratulation, your problem solved.....

seriously? change wire harness is such a big issue is it? does the harness wire was build to last a lifetime? ya,will be doing a complete check and see if the problem arises after a few month.

anyway, i've already checked with the SC, the ignition coil assy does not need to changed as it is build to last until 250k km.. and the ignition coil assy is still ok based on his story..

Wire harness of the car is like the blood arteries and veins in human. Connects the ECU to every part of the car, that is engine compartment, under the dash , under the carpet too for connection to the rear for control of the lights behind.
There are many many tiny wires inside all wrap up, so if there is a fault, they cannot pinpoint where, then the whole harness have to be changed.

Now, I wonder how come SC have expensive sparky also?

ya, they say, aybe the on that they changed got some problem,so they changed to a newer ones at no cost..

earlier on, they could not detect the problem because simply the problem does not occur when the car was with them, the second time i handed the car to them, after a few days, then the problem occurs. then they start bombing me with phone calls telling that this might be ECU problem, spark plugs problem, throttle body problem, piston problem, wiring problem, transmission problem and so on..so many problem might just change to a newer car liao..

they changed it for free..so i get my old old spark plugs back which has only run for 40k now..still left another 60k on the spark plugs life, the second spark plugs in chich they say was faulty and it only runs for 5km oni..haha..they gave me for free lo..what to do..


back then, they have this promotion on the denso iridium spark plugs..but i'm not the one who sends the myvi for service..so my dad changed from the regular spark plugs to the new iridium spark plugs which cost 180 back in 2010..now dunno how much liao coz already 2011..and they only stated FOC for the denso iridium spark plugs on the paper.
