Water pump and MAF Sensor

Yes, I've been very quiet lately and that's because I have been busy with work, away for a nice diving trip but generally, not wanting to spend anymore $$$ on Miss Red until the situation with the bank has improved. This car was never intended to "stimulate the economy" but seems lately, she's been doing a very good job single handedly helping Ah-jib-gor, Mr.PM cum Finance Minister do this! And that b*st*rd tear gassed me the other day. MF.

Alamak... Ma'am, you also "Kuning"? 

OK OK, enough of the bitching.

After a good, short yet exciting, spirited drive last night - my dear decided to give me a nice birthday present after I switched her off.

When I drove the car out this morning, the car had no power and was practically running at 20km/h even on wide open trottle (full flooring!!). Parked the car at the side and as the car warmed up, it started to drive ok but seemed to still lose power at top range of each gear.

As I got closer to the office, I was really stepping on it only to keep it at 90km/h. No choice, detour to my mech to check her out. As I was driving there, I was wondering if I screwed the gearbox last night with the high revs. Luckily, mech told me these symptoms don't point to that (yet other smaller things are hinting at it - some have to be careful).

The suspect was the ignition and he proceed to check the plugs and the ignition coil. Lucky all 6 was ok. After taking it for a test drive, he came back and told me "Mass Air Flow - MAF" Sensor kong. He took out the cable connecting it (disabling the reading to the ECU) and the car could drove like normal. However, driving without a MAF mean the car will be drinking petrol as there is no sensor to govern how much air-to-fuel ratio to mix.

Mass Air Flow Sensor - Air pass from left to right. Signal sent to ECU via bottom 

Small sensor detect how much air is passing through

Air from air filter pass through MAF before going into throttle body

Unfortunately, we also noticed water started to drip out to the ground. Further inspection showed that the water pump had given way. DUIT LAGI! When he took out the original water pump, it looked really shot and I was convinced that this was more of a wear and tear than anything else. The water pump looked like it was never replaced or a long time ago! All corroded and the gear was also shifty. This morning's episode probably just accelerated the date of death since I was flooring the car and this in turn just turns the pump much faster.

E39 Water Pump

Everything seems back to normal and I've noticed that the fuel consumption has improved ever so slightly. Let's hope this can at least make me feel like this whole ordeal was worth it!


Luckily, this event was shared with the 2 guru-gee who help me pass time following them do their stuff. Red Arrow sprayed his big scratch (due to some vandal's itchy fingers!) in record breaking time - and not to mention record breaking cheap! Black Beauty now has 4 fresh new brand spanking tyre and a pair of "chun" no. plate.
