One of the fuel injectors (#4) on my 2000 GX broke this week at 73k miles. Check engine light flashed and engine ran rough. The last injector (#3) failure was just over a year ago. It is now covered under emission warranty but the warranty is going away soon @80k
. Parts and labor cost is expensive - around $800 each at dealer if no warranty. Wonder if this high failure rate is caused by Honda's manufacturing defect or caused by other components or the gas.
I have kept up the maintenance and even changed gas filter a few months ago. Anyone else has injector failing before? Any suggestions to avoid another injector failure?
