yes , it decrease abit then back to normal again...

You might want to check with Zordaq see if they got kawan in Melaka knows how to fix IAFM. If your IAFM shaft not yet broken then still can repair punya.

Worst case is to visit their KL outlet for the fix. Zordaq JB charged me RM50 for the repair.

Not yet fix bro?

I see thanks, I read a workshop in Melaka do provide the IAFM services, but they haven't reply my message yet. The shop name is Dori's btw.

Haven't send back to proton... Outstation now...

Do check on do they repair the valve or they remove it. Some workshop eliminate the noise by removing the valve, so you going to have no IAFM for your low RPM fuel savings. Zordaq's way of fixing is add a washer-like tube to stabilize IAFM shaft so it won't rattle.

My gut feeling is intermittently failed fuel pump. Just blind guessing. Have your technician check beyond electrical and intake controlling system?

the mechanic just replied to my msg just now, he confirmed that they will do mod/upgrade on the shaft component itself, removing the butterfly is not a good thing to do as it will effect the performance and fuel efficiency depending on the condition of the car. The price quoted is rm180, not very sure if the price labour charges included. But anyway, still cheaper than few workshop offer me around rm300 to up than rm500.

their price increased it seems. few years back my friend's saga blm repaired by them, around RM80 that time.

Ah I see.. thanks for the education!

Bro, may i know how long you've had your belt tensioner?

Mine screeching early morning even thought it's just about 15,000 km long only. Zordaq used the CFE tensioner on mine citing the thicker shaft of CFE tensioner makes it more lasak.

Don't know is isolated case or not but i got a bit regret going for CFE tensioner.

just want to share. i only changed the coolant together with timing belt. other than that, nope. and it's working fine. now clocking 190km, so, twice change timing belt, and also twice changing coolant. yes, me too using stock proton coolant..the only thing that i changed on my car is the extractor and the HU. others are stock. even the stock front abs is still performing fine until now. the a/c i never serviced. it's still just as cold. 2011 persona h line.

parts that finally damaged since ownership:
1. drive shaft (left)
2. crankshaft sensor
3. Rear abs

and, that's it.

mind to share how to know when drive shaft damaged?

common tear and wear parts on persona. replaced it twice on mine, but it's just easy to DIY. just need to take off the ignition coil and open a few bolts. release a couple of hose, and unplugged the co2 sensor. take off the old seal, clean the remaining old glue on the rocker cover with a scraper, install new seal and glue it a bit, and reverse the process. total cost would be less than rm50. latest im using the silicon seal. still remains to be seen whether it is better or worst than the common rubber seal.

mine damaged on the inner side. the one connected on the gearbox. on physical inspection, you'll notice there's freeplay on the driveshaft. but obviously, you'll only notice that if you uninstall it from your car.
while driving, you'll notice your car shake when you push your car torquey2 a bit. ha ha. or, like mine, on 100kmh, my left side of my car will vibrate like hell. even the front passenger seat is vibrating.

normally, if you hears that tak tak tak sound during cornering, usually it's the cv joint.

oh okay, thanks for the clear description

i cant remember but it could be around 35k - 40k km..i think i changed it every time i change my timing belt..

How much it cosst for each of them?

Thanks for sharing.

How about Power Steering oil? Have you change it?

My previous tensioner also start giving noise around that mileage. But still can last until 80k km and change with timing belt.
