hi guys,
need some help/answers here pls,
why is the engine jerking/hickup when stop on Drive mode on brake pedal ? When stop on Neutral mode, less pronounce of engine jerk/hickup,
i have cleaned the AFM and all socket connections with proper cleaner/de rust, it improves a bit but the jerk/hicup is still there, anything to do with throttle body?

badly need advice/opinion, as tis jerk/hickup is driving me crazy!

thank u guys,

coil plug may also be the problem.

FYI, you need to make sure the chop shop injector are similar cc rating else you will get lean burn and it will burn your engine.

hi,
the jerking is minimised, after changing to a second hand AFM of a later model,
but the engine pinking/knocking still persist! Mostly during the day when its hot, no pinking when raining or night driving. This is mostly temp. related, but .........No ideas - solution from anyone?

thanx,

the prob with halfcut items r they might not last long n if u r driving a 3.0, the injectors r different from 2.0 or even 2.5

unless u r sure its from 3.0, else u will face probs like what weikee stated
Yes, i agree with Ong , Chopshop parts depends on your luck, sometimes is can last for long time other time terrible!You know wat , I have similar problem last time , went to tc shah alam , unable to fix , outside mechanic also fail to fix , Items checked and replaced 6 coilpacks (RM200-00 each), Knock sensor (RM687-00!), TPS sensor, Engine tuning (RM105-00) , Intake manifold & valve cleaning (RM150-00), Rubber hose(Joint between T/B and air filter maf sensor ),Intake manfifold gasket (upper half) , oil sealed (seated between injector and intake manifold), Cleaned tb (became worst). Even did some resistant and voltage test on the electrics, wiring and connectors, no luck . Well, only 1 thing i didn't test/replace that was the injectors.
