Causes of high fuel consumption. Updated 26Jan2007
Im having the same problem. full tank will last ranging from 340-370. but im on auto. normal drive. nv rev up more than 3k rpm b4. shit man. wats wrong wats wrong?pinkielouis wrote:hey all bros here... i seriously need some help with my eg9.... i pump a full tank but up till almost empty (almost touching the last marking) i can only travel up till 340+ and i nv on my vtec.... any idea what the hell is wrong with my car....
dont quite understand yr prob. need to describe abit more clearlytensaixp wrote:hi, recently my car sometimes accelerate rpm like stuck, then after while like the resistance release then rev cont to climb. n fc is damn bad, used to clock 11+, now less than 10. dunno if its coincidence or wat, but it happened not long after i change 4-2-1, decatted and retuened afc...

B) Faulty coolant temperature sensor (usually common in wet weather)
This is connect to yr engine header to detects the engine temperature. It will feedback to yr ecu to adjust yr fuel map.. if it detects temperature below 80degrees, ecu add more fuel. i havent heard much people change this sensor coz in most times, we are worried more on overheating prob than colder temp. But it can be a prob with fuel consumption when the weather is cold. Mine went haywire recently and i detected it thru a digital meter.. bought a new piece at less than $30 fr Tanly.
Unless u have a digital water temp gauge connected to this sensor, it is quite difficult to detect this prob
hi, my water temp gauge reading 80-82 deg when car is stationary. But when car is moving, the gauge reading start to drop to 50-60 deg, sometime 40+. The temp shoot up again when car is stop, I think the gauge got no problem since the needle can move up & down. Is it the water temp sensor problem? Pls advice. Thanks...

Bro is your fan working?. Maybe just worn fan bearings . Your fan moving at slower speed to cool the radiator.Since the meter shows lower temp when u drive.Goofy7 wrote:B) Faulty coolant temperature sensor (usually common in wet weather)

yr temp fluctuate too much to be normal. wat does the analog water temp in yr speedo shows? My guess is:Goofy7 wrote:hi, my water temp gauge reading 80-82 deg when car is stationary.

1) water temp guage wiring never install properly
2) water temp sensor spoil (but u would have felt poorer car performance)
3) no thermostat (abit unlikely)

50-60 deg is too low leh .. normal is abt 80-95 deg ba
there is a small rubber pipe fr the intake manifold to the fuel regulator. Plug out the pipe to get the pressure readingpgm iv wrote:bro what do u mean with out vacuum?garilee wrote:b16/d16 is same abt +/- 3bar without vacuum.pgm iv wrote:hi bro what is the stock fuel regulator pressure for b16a engine? thank
