Well, installed my 60's with my new tune from Allen Nelson this past saturday... I got the injectors from Jon at FIC and supposed to be direct fit. Now these codes keep popping up, i have looked for vacuum leaks, sprayed brake cleaner around each inj and around the hoses and still no luck.. Could it be in the tune, O2's getting weak? Im lost any help would be appreciated...

 

Doubtful that both sensors die at the same time. Sounds like you have the wrong injector size. When I say that I mean you were told that they were 60's, just verify they are. Also the Injector size for a vacuum referenced regulator vs a non referenced regulator are going to be different. If all you did was change injector size/injectors and your getting lean codes, your problem is there in one of the two things that you changed. Do you have a way of changing and reading your tune. If you have it post it. Can you hook a scanner to it and read your short terms and see how much they are trying to add?
