  1. Got in my 1988 Nissan Pathfinder this morning and it is running extremely rough all the sudden.Then it would stall either during idle or while driving if I let off the gas pedal. The truck starts without any issue. Not really knowing where to start I first cleaned the distributor cap, contacts and rotor but that didn't help. I also checked the spark plugs and fuel pressure and those are good. At that point I pulled Error Code 11 Crank Angle Sensor/Camshaft Position Sensor from the ECU. So am I wasting my time doing any further troubleshooting other than just replacing either or both the distributor and Camshaft Position Sensor?
  2. 1) The bottom AB Valve (90 degree) Hose on my 1988 Pathfinder just split and I can't find anything to replace it with. What do I do? I believe this is part number #14864 (Hose-Ab Valve To Inlet Connector). I went to the auto parts store and they were not helpful. https://www.nissanpartsdeal.com/parts-list/1988-nissan-pathfinder/engine_mechanical/secondary_air_system.html?pnc=14864&diagram=148_B01 2) Also, the bolts (Part #16500A) that hold the air assembly to the engine are missing. What size bolts are these? https://www.nissanpartsdeal.com/parts-list/1988-nissan-pathfinder/fuel_engine_control/air_cleaner.html?pnc=16547&diagram=165_C01 Thank you.
  3. My 1988 Nissan Pathfinder is in fail-safe system operation and stutters when rpms rise above 2,800. The ECU's self diagnostic systems displays code no. 51 (Injector). I tested the 15-pin ECU connector and I have no voltage between terminals 101 & 102 and 114 shows voltage of -00.1?? and terminals 103 and 104 both show 12.85 voltage (good). This appears to indicate that one of the injectors is definitely bad.? Can anyone confirm this? If one injector is bad then no further troubleshooting is required as I plan to replace both injectors in that case. Which brings brings me to my next question. I would like to do this repair myself but I am novice mechanic and not sure I can do it myself after reading the replacement instructions online. But I am in a bit of bind here because no repair shop I have called in my area will touch it. They all say it's too old.
