Hello, I have a 1996 Nissan XE pickup with the 2.4. With a standard transmisson and two wheel drive. The truck has a low rpm miss, but is throwing no codes. I have replaced the EGR, MAF sensor, Crankspeed sensor, fuel filter, and the Catilytic convertor. Also it had excessive valvetrain noise and we flushed the hydraulicrockers, the cam whenpulled looked good.I have had no luck elimanating the problem. Can someone help me with this problem?
