    1988 Nissan pulsar Nx Se Misfire !!!! help !!!!

    I have a huge misfire in my 1988 Nissan pulsar nx se. i replaced all the coils, and spark plugs. i tested the wire connectors to each coil pack and they are reading but when i unplug the 4th coil pack from the engine it does not effect the engine. what is the cause of this? and also could anyone tell me where the vehicle spped sensor is and the knock sensor is on this car?

    If the coil is working it would be down to the spark plug, fuel, or air in the cylinder. I would check the plug since it's the easiest, then go to the fuel. make sure your injector is working. and if those are both working the only thing I can think of after that is a bad valve. it's even possible that the butterfly in the intake manifold came loose and is blocking flow to that cylinder. although I haven't heard of it on the older styles.

    It can also be cause by a fulty ignitor module also. The loom that connects to the coil packs the other end goes to a ignitor module. May need to swap that out

    1988 nissan pulsa r nx se

    Hey guys thanks but i know the injectors are all working and the only cylinder that is not working is the 4th one. Could the ignition module have anything to do with this? if so where would i be able to get one for cheap or does anyone have one they are willing to sell or give away? Thanks in advance !!.

    The ignition module can cause that issue yes. Ive had it a few time on mine.

    You can find them on ebay. just search ca18 ignitor.

    Can the ignitor module cause one cylinder or coil rather to lose power?

    The speedo should be a cable. So that would be that the cable is broken or the plastic that attaches the speedo to the cable. Speed sensor might be the issue of the tach. But I think the more reasonable thing to assume would be a buildup of rust or something causing resistance. And it doesn't give it enough volts until it hits 5 to make it move.

    I have no idea. Probably a shop. But when my plastic piece broke I just fabbed up a new one and it worked fine. I would take the cluster out and see if it's broken. Because it's more then likely just that bit that broke.

    Find what cylinder is missing. By unplugging each coilpack 1 at a time. If you unplug it and there is no change to the running you know its that coil pack. Move that coilpack to another another cylinder and see if the miss moves.

    If it does its the coilpack. if it doesnt id check the injector

    The fuel injector is firing and im getting spark. could a burnt valve be the problem? and also do you think these cams shaft would fit in a stock ca18de without any problem or having to change anything? Procam CA18DE(T) Solid EX 270-9.25mm by Tomei
