Minor Threat

Can you grab another WB to check with? Perhaps your's has taken a ----.

I thought my WB would be bad, but its not. If I increase the injector % in my ecu the air/fuel will get richer, and if I decrease the injector % the a/f will get leaner. So I know that works just fine.

well I just got done replacing the injectors and its doing the same thing. I also checked voltage at the fuel pump and it has 11.5v with the ign on.

put in a larger diameter fuel return line. not sure if it has anything to do with the problem, but when i added a larger capacity fuel pump i had to increase the size of my return line. the car was acting funny and surging and bogging related to fuel pressure i thought... when i put it in it seemed to help. i think at this point you're willing to try anything.

i could be way off, but i remember reading somewhere that increasing fuel pressure is more to atomize the fuel better and not really to get more in, so if the fuel is getting broken up better then it will burn better then the WB would show it being leaner. also, if you are running 1000cc injectors then you have to be using some sort of computer control, why not just richen it up with your fuel map? again i could be way off, my car isnt boosted yet, but i am running 450cc injectors with uberdata.

I did put in a AN-6 return line with braided hose. it made no difference. But yea, right about now im ready to try anything.

98ctr

I could just richen up the fuel map, but I feel like im covering something up thats not working right. So I want to make sure that it works right before I end up tuning the boost.

maybe your lines are too small now??

stock lines should be more than enough at idle, don't you think.

have you thought about trying out another car like joshes dad's to see it reacts the same to fuel pressure adjustments at idle? sounds stupid but maybe its just some sorta fluke?
