Sifu, I got problem with my 3 year proton persona. Sometimes when I driving (don't matter city drive or highway), my car somehow like losing power but the engine still running.

Its didn't turn off but others like car lamp will blinking, air con/radio will off and on and my light of car meter will fade and come back again. All this happen together. I sent to PJ car centre before & they just told me the car fixed by reset the timing. But 4 day after the services, the problem came back.

Ask my friend father who is mechanic. He said the problem might be wiring problem or purge valve issue. I sent my car to same service centre & highlight the issue to them. After checking, they said no such problem + they reset the timing again.

My warranty almost done by next month. I afraid after my warranty KO, then they will ask me to change this or that. Can sifu help me on this? Other Services Centre recommended?
