I talked to the same service guy this evening, he said that although the PDT did not detect any fault with the car but he strongly believes that a particular relay maybe defective. So I straight away told him to order the relay. Will replace the item next week and see how it goes

Hmm. Odd enough. I heard many times. My case is i stopped, open my house gate, then drive up.
Let the car roll in then suddenly jerk.

Did you sent your car to any service center to check the problem?

If you have rectified the problem other Persona users can have a better idea what may have caused it and how to rectify it

Certain thing you get SC to do they are hopeless. Have enough of them so now service Tiggo outside also.

I just went to the SC and paid RM87.99 for 1 unit of ICM RELAY Part number PW892520 (Proton Genuine parts). This relay controls & regulate the fuel system in the car. Will get it replaced next week. Hope that this will solve the problem.

Last Thursday, I poured Bardahl Injector Cleaner in the fuel tank. Since then the car does not jerk anymore. The rhythm of the engine sounds smooth, back to normal as it used to be. Could it be that the Injector cleaner has helped to solve the problem? I don't know but I will observe the situation for a few days more.

Weird. Injectors clogged should affect you throughout the rev range, not just at idle.

nope...not the injector.
certainly not the injector
