Dear Cefi Sifu,

I experience in several occassion that my cefi A32 2.0 engine sudden turn off while driving.
First I thought is the spark plug that cause the problem but when I send my car to my mechanic .. it seem the car is ok upon clearing all faulty code.

But recently it happen again and it happen more frequent. Is this cause by fuel filter clog..?
or any other part that I need to change or service:hmmmm:..? PLEASE HELP.. Thanks

Dear Bro,

I had the same prob with my ceffy a few months back...Tried and changed all sort of things from petrol fuel filter up to new spark plug but still can't solve...check with TC and there's no error code pop's up. At last change an AFM and everything were solved.... .Just check your Air Flow meter before further action...:driver::dancing2:

Chop shop selling used AFM around RM 150 to 300 depend who you know, and where you buy. New one i think 1k plus..

My call loose power during low end and sometime stall due to harden inlet manifold gasket, that may be to problem too.

This are the common problem in a32

1) AFM
2) knock sensor
3) inlet manifold gasket
4) ignition coil
5) dirty fuel filter and air filter (will reduce engine performance)

wow, fuel filter so x-pensive. i remember i chg at aprx rm 20 niah.i also encounter engine die off when driving.1st time it was AFM change AFM solve problem. 2nd time was after AFM box hose connector putus so AFM cannot control.

2nd happen time is due to hose/tube is already harden when foreman dismantel hose accidentally break off then he told me this one no problem one. when i start engine can start when press a accelerator engine die off. sometime start also die off. so he replace me 1 set fix in wah lah problem solve.

I cange my oil filter for Rm 24 only inclusive of labour charge. New FM will cost you a bomb@1.8k fm TC. Better get one from chop shop. Got mine for rm220 @waranty 1 mth. Check the AFM hoses or box for any leaks before changing the AFM.:driver:

arun2121, Fuel filter is more expensive than Oil filter, and better to change every 60kkm

I change air filter every 25 - 30kkm, and fuel filter every 40kkm, you should see the dirt drop out from the fuel filter, is very dirty.

Changed b4 the fuel filter , located near the firewall, quite difficult to reach , make sure you have alot of old clothes/rags below the fuel filter and PLEASE RELEASE THE FUEL PRESSURE B4 DISMANTLING THE FILTER. Get ready to wipe off the petrol around the firewall.

AFM would be easier to replace but the 4 screws attached to the AFM will be difficult to release coz its not everyday we open up the AFM.(The screws will likely lock up)

The above DIY are quite tedious to do but doable as long as you have patience and the correct tools.

**NOTE: I've heard some owners changed to Z32 AFM with a bit of mod, seems to increase airflow for better performance but i 'm a bit sceptical whether it would run properly during normal driving.

afm is easier to replace if you are the diy person especially good in the engine bay. If you are doing the afm replace, you can ground the afm also. You need to find the afm gound signal. i did it when 1 first take the afm to clean. Need to locate the afm gound correctly if not you may fry the ECU. (I assume you are the advance DIY cause you mention installing the Apexi Auto timer)

you can trace the ground by

01) Tracing the ecu cable. You will need this too when you install the Apexi Auto timer.
02) service manual.

Change fuel filter is not a real technical job, but the hose are so "DARM" tight and is really really hard to pull it out from the fuel filter. I can replace the AFM in 10mins, but fuel filter take minimal 30mins. If your fuel filter are really old.. My advice is to change the inlet and outlet hose together.. is faster.

SB3, is not worth the effort to change the A32 AFM to Z32, the investment are too much for the small gain (if any). Unless you plan to install the E-Managed, and force induction the engine than you can think of this path.

XTEC, for standard is not worth the installation and price.

Emanage can use for AF adjustment, timing, increase engine rev, and many more. Without any engine enhancement, most you may get maybe 5 - 10% extra, if you already got one than give it a try. If install properly and all the wires are connected, it can do lots of things.

Beware, not many installer know how to install all the feature into the A32 cause is not common.

You can read up this article from VQPower,

Swap the MAF and check any leaking rubber hose after it for leaks.

bro adjust your throttle sensor turn it clockwise and you will find the engine will try to die off.then turn again the other way until you feel the engine rev up then back up about 1mm ...that may the fix you will see the 2 socket on top of the sensor near your throttle body
