Hi..



Hopefully i can help..



There maybe a few reasons for this to happen - the first obvious would be the quality of the coils your putting in - as in some cases putting in cheap coils can often cause this this problem as apposed to direct from Nissan replacement coils which would most likely be of better quality,i'm not saying all cheap coils can be like this but something to bear in mind aswell as too it is often best if one coils goes then your are much better off replacing all at the same time - other areas would need to be investigated ie: - pretty much "all" engine earth points and make sure they are all still intact and clean and not corroded etc as bad engine earthing could cause this - too check the wiring from the defective coils/plugs back to the ecu for any possible damage/chaffing etc - aswell as the ecu multiplug pins/wiring for corrosion there too - The ECU itself is pretty much the driver for the coils so there is chance or possibility the ECU may likely be defective and causing the coils to blow or burn out continually - Unfortunatly the only way to tell if the ecu is suspect is to have it removed and sent of for proper testing if you don't have anyone locally who is able to carry out such testing or checks too see wether the ecu is cause of all your problems..
