Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I think you are on the right track with the ignition system. I can tell you from experience that these ignition systems are picky about aftermarket parts. I would say that if this is not a cap or rotor problem that it could also be a problem with the coil producing weak spark. There is also a sensor inside the distributor and sometimes these sensors can get oil on them when the distributor shaft seal leaks. I would look deeper inside the distributor. There is a metal plate that is behind the rotor and held on by a couple screws. Take that plate off and see if there is oil collected behind it, If i was going to replace any part of the ignition system I would use parts right from a Nissan dealer even though they might be a little more expensive.
That's good there is no oil in there. Does it only act up when it is first started? no problems after it is warmed up? Where did you buy the cap and rotor and wires? Are you running NGK spark plugs. I can't stress enough that these systems do not like on OE parts.
Depending on how much oil is accumulated in there you might be able to clean it out really good with brake parts cleaner and get by for awhile, however, the seal that is responsible for that is inside the distributor and would require replacement of the distributor housing. Problem with that is most people go and get a remanufactured distributor and then the whole parts quality thing comes in to play again. If I was going to get a distributor I would get one from Nissan or understand that you might get a faulty one if you go aftermarket. if you are going to try cleaning it out I would get a new ignition coil while you are at it. But guess where I would buy the coil?
Hope you got your issue resolved.
Thanks , good luck
