AeroGrace Posted September 30, 2003 Share Posted September 30, 2003 over-fuelling does rob you of some power i believe... Link to comment https://www.sau.com.au/forums/topic/25949-loss-of-performance-with-faulty-02-sensors/#findComment-550639 Share on other sites More sharing options...
G0DF4Th3R Posted September 30, 2003 Share Posted September 30, 2003 yeah it does rob you of fuel thats why u try to run leaner than stock but not to the point of detonation Link to comment https://www.sau.com.au/forums/topic/25949-loss-of-performance-with-faulty-02-sensors/#findComment-550643 Share on other sites More sharing options...
Boostzor Posted October 1, 2003 Share Posted October 1, 2003 Buy another one for around $100. They are the same as the O2 sens on the EL falcon. Pull the old one out, put the new one back in. Apparently they should be changed every 50,000kms so chances are the stock one u have in ure 'line is worn out.

N/A® Posted October 1, 2003 Share Posted October 1, 2003 U dont loose power as when u are accelarating. The ECU does not read from the O2 sensors. Wide open trottle has no effect from the 02. They only trim fuel whilst cruising levels.

R31 POWER Posted October 1, 2003 Share Posted October 1, 2003 I think you have to cut the plug off the R32 one and put it on the el one Link to comment https://www.sau.com.au/forums/topic/25949-loss-of-performance-with-faulty-02-sensors/#findComment-552150 Share on other sites More sharing options...
Gradenko Posted October 1, 2003 Share Posted October 1, 2003 The O2 sensor is also used during a cold start, at least it is once the sensor heats upto 800degC and starts operating. So a slow reacting or broken O2 sensor could cause the car to stumble and feel slugish while the engine is warming up.

pawson Posted October 1, 2003 Share Posted October 1, 2003 Where can I find the O2 sensor? I've got problem in cold start. Want to check is that the reason Link to comment https://www.sau.com.au/forums/topic/25949-loss-of-performance-with-faulty-02-sensors/#findComment-552171 Share on other sites More sharing options...
Gradenko Posted October 1, 2003 Share Posted October 1, 2003 pawson, the O2 sensor is screwed into the dump pipe right after the tubo. Don't assume its the O2 sensor straight off, it could be anything from incorrect heat range spark plugs to the thermostat. What sort of problems are you having?

Jamezilla Posted October 1, 2003 Share Posted October 1, 2003 my mates is dead and it just used lots of fuel when cruising blows a good flame though on gear change Sounds exactly like my car. Fuel economy is shocking - but the flames are fun. Getting 02 sensor replaced on Monday. Will let you know how it goes.
