hey guys i have it running i just have a question on o2 readings. my lft o2 is reading when warm that is, 800 down to 50 i compared it to the rt side and it is reading from 900 to 200 and the lft fuel trim on the lft is 106 and the rt is 128. i hope this makes since these readings are while the car is running. the lft o2 is a new bosh unit and the right is factory one. is this ok or is the boch one bad? or should i ck the plugs well im going to do that anyway.

 

ttt noone????

 

50mV - 900mV is normal range. 200mV - 800mV is still normal range, but the sensor may be getting "lazy".

The 106 fuel trim indicates that the PCM is taking fuel away from that bank of cylinders from a perceived rich condition. 128 indicates Stoichiometry (ideal Air/Fuel mixture) and no adjustments are being made.

I would swap sensors from side to side and see what happens. If your still 106 on the left and 128 on the right, then bank 1 (left side) is running rich (perhaps stuck or leaking injector?). If the fuel trims swap sides, then one of the sensors is bad.

 

cool thank u for the info. i will do that.
