Hi Law,
Other lucky guys found out a bad sensor when they have bad FC. For me, my feilo just got a fuel cut and dies by the highway. Cost me RM 70 to tow it back to Sri Petaling Friday night.
Workshop quoted me RM 700 for the sensor, Vanli quoted RM 480 but will call me back to confirm.
Recently my full tank can only give me 300km, change Knock Sensor (RM380) and O2 Sensor (RM340) also not help.....still figuring out why......
Before the failure, dont you find any problem in terms of driveability? Any error code?
Below is copy and paste from autoworld.com.my
Symptom
> Pick up and mid range torque slacks
> High FC - sometimes very very high
> sudden black smoke from the exhaust emission
> RPM inconsistent - sometimes driver feels that the engine gonna die off
> Fuel/Air mixture percentage not right (can be seen on the diagnostic device in graph format)
> Sudden vibration felt from the engine compartment during idling especially during long heavy traffics
What are the main causes?
> most cases were due to bad air filtering - means very dirty air keeps on coming into the throttle body. Always use the correct air filter.
> leakage on the air filter housing especially the one close to the throttle body (the flexi type housing)- faulty rubber seal or pin hole on the housing.
Early prevention is very important, else the problem might spread right into the throttle body, the Idle Air control valve, the Throttle position sensor, the fuel injectors and so on. In long run means big $$$$$. So, don't "cheap-skate" on filters.
