Fuel injector reliability

[Saabjock]

How leak prone are the fuel injectors in the 2003 Nissan Pathfinder with VQ35 engine?
I suspect I have one leaking and if they are, I may consider a different alternative.

202k miles on my '02 and as far as I know it still has the original injectors. What makes you think you have a leaky injector? What issues are you experiencing?

I thought I had a bad injector but it turned out to be the fuel pressure regulator. After hours of research I never found anyone who replaced an injector.

Throw in some Techron quarterly and I think they will last forever.

Replaced my #2 fuel injector at 205,000 miles it started leaking into cyl #2 causing misfire. Its more likely to be clogged or seal wears and it leaks into the cylinder. I would run Royal Purple MAX injector cleaner in 10gal of gas should clean them up nicely, my symptoms were P0300 muti misfire I ran 7gal of gas and full bottle of royal purple max injector cleaner that cleared up and got p0302 cylander 2 misfire but my symptoms were hard starts poor acceleration and hesitation at high speeds flashing CEL when it got real bad
