Hi guys, to make this short, I have put 2500 kms on my new engine that was rebuilt last winter with all OEM stuff, oem pistons and rings. Ever since the rebuild the car dosnt run right when I have my oxygen sensor plugged in. The first o2 sensor was brand new from nissan and the 2nd one was a used one off a friend of mine. The symptoms are as follows: the car runs very lean and I feel a big lack of power even in boost when the o2 sensor is plugged in (i tried both, one at a time). I have been running the car mostly without and o2 sensor now and this problem is really getting to me ... does anyone know what can be the problem ?
The car is bone stock except for an air filter + hks ssqv blow off valve.
