Most probably there are leaks when installing the new extractor, or the oxygen sensor spoilt due to poor handling when installing the new extractor. Dont think is your ecu problem

If you can borrow an O2 sensor to test will be good.......

Hi, i already replace the 02 sensor but problem still occur. This is the error code p0131, 0132, p0172
Usually only one error code, but yours have 3. One is low voltage, one is high voltage , and one is rich air fuel ratio, this really have to trouble shoot....

Those error shows when i rev at 5 to 6 k rpm.. below than no engine light. Is is possible due to location of the sensor? Or maybe due to wire extension made by the wshop

Yes. Extend the wire by simply cut it and solder with other wire.. i'm suspect this issue might be due to this or different location of the oxygen sensor. Will try to locate the sensor back to previous position

Was about to mention sensor location, since you had no problems before mod. Now you mention wiring can be affecting it too....

Hi All, just managed to figure out what is really happening. Last pomen didn't connect the wire correctly and create wrong connection. Now everything back to normal. Thanks all
