I have a '87 Pathfinder that is a v6 it starts when its cold but when it warms up the RPM gauge starts dropping but not with the motor then the motor dies. I change the starter, coil, and distributor. Ran the codes on the ECU and it says theres nothing wrong. Does anybody have any idea Whats wrong? I had problems with it a year ago and it wouldnt start and it ended up being a sensor on the transmission that had something to do with the floor shifter indicator not working but special order the sensor and it started and the indicator worked. Plus A new ECU is Like $375
