Here's the problem, I bought a new F.I., it was installed, after a few days, the car was running rich, and flooding out.
Found out I was sold the wrong injsector, (Pink Dot) so got the right one (green dot). Installed, the next day, same thing. Next move change the brain, same problem, but had not change the injector.
Changed the injector, car ran great, but was leaking gas from new injector. Change "O" rings, car ran great while idling.
drove the car for 20 minutes, no problem.
Got back in the car 3 hours later, same problem.
Question, should I just change all the injectors, thinking they are a matched set? Or Im just blowing out "O" rings cause they are not the right ones?

Help!

 

if all the other injectors are in spec...I'd say its the O-rings, but its kinda funnny since its not a constant prob and is delayed over time. after I did my injectors on my 91 Maxima it took 2 tires and some motor oil to get the rings in without pinching them(thus leading to the leaking, etc.), but my probs would start as soon as the car would come on, not 20 minutes or 3 hours later...strange.

 

Also, when we installed the last injector, number 5 Injector spot is where we would install the new one, we took an old one, placed it in the number 5 spot, and put the new one where the old one was.
So not the problem is in the nnew spot with the new injector.
Could I have gotten bad injectors 3 times?
