iafm proton saga blm

i learned a new word today - iafm a.k.a intake air fuel module.

recently, my proton saga blm began to make this irritating knocking sound so i went to the mechanics to check it out. the first mechanic i went to told me to flush my engine with an engine flush and cleaner - specifically, a product by würth. but the thing is, i have to use it a few kilometers before the next service and leave the engine running for about 20 minutes before changing the engine oil. my car was serviced like 3 days ago. tak berbaloi. lagipun the mechanic said, maybe akan hilang bunyi tu. maybe is the key word. not good enough. so i asked him to give me an absolute answer. how do i make the noise disappear? his answer, replace a part of the engine (sorry, can't remember what part) for rm1k++. but that's not the exact figure though because he has only done it for mazda cars. not proton. okay.. never mind.

the next day, a colleague proposed that i should try asking other mechanics and compare answers. hm.. good idea. but where exaxctly should i go? he suggested a mechanic nearby the proton service centre. then it hit me. proton service centre kan ada! around 7 minutes drive je pun. haihh. why didn't i know that? padahal dah 8 months kerja around this area. so off i went to the proton service centre.

and that is when i learned this so called new word. iafm. the mechanic said i can get it replaced for rm200++ not including labour charge. two different answers from two different mechanics. but i am placing my bet on the second mechanic though. because he works at the proton service centre and my car is a proton. duh! but anyways, since i now know what seems to be causing the problem, i decided not to place my order yet. i need to do some research first.

and.. the second mechanic may be right! google told me that other proton saga blm owners have had the same problems as mine. i consider myself fortunate to not have it replaced sooner. some owners reported having it replaced at less than 10k km mileage. my mileage is now at 160k++ km, 2009 edition. so maybe the proton r&d team did make some improvements on the iafm they installed previously. err.. thanks?

proton still has a long way to go.. *bittersweet emotion*
