Any sifus know why my car will jerk, almost everytime when i maintain my speed at 40-42km/h ???
the type of jerk gone worse...last time only jerk 3 times, now is continuous non-stop at that speed....i have to either release pedal or press it harder, so the jerk won't happen again....
i am using Auto gear(not in shiftronic)....my model is 1.6SX...when i go SC, they oni use computer tuning, and always no problem found in computer reading...for wat i know, is nth abt computer reading or anything related to ECU...
wat's the cause of the problem?? it happens after my 1k service...change engine oil, oil filter, and ATF fluid....all caltex brand......

can any1 tell me hw 2 solve this problem?? coz the problem had gone worse....i nid advice from SIFUS here....
i doubt the SCT won't know hw 2 solve this problem...

i see, will go do check the balancing....
balancing can coz this problem?? but only between 40-42km/h only...

and..wat is drive shaft??

=.=''
this is a really big problem....
i nid 2 knw wat causes it...

i've tried R97 petrol....caltex,BHP,V-power...also the same..
it happens when spd 40-42km/h in 3rd gear, which RPM is low.

not below 1k, is around 1300-1400 RPM

yea, i did that ald, the technicians always take my car out, n come bck say no problem....
or else if hv this problem, they will take a laptop, plug in to ECU and check for errors...and always say no errors
then they say this...'it biasa saja, x kan kacau punye...'
n wat 2 say??? they oni check ECU for errors, din even check c the ATF fluid and drive shaft

i went there ald 3 times, all they do is, take laptop and check ECU...and always say, no problem found....sure la!!! got nth 2 do wif ECU 1...bodoh technicians...
