running rich

Ok so i finally got my car to run and idle..yay

now...it runs alittle rich, im guessing because of the 30 lb injectors.

Any tips or tricks to get her to run not so rich.. i changed the prom over to 30lb injectors...i decreased the fuel pressure.. anything else i can do?

What do you mean? Did you just change the injector constant? If you have the ability to do that then just look at the fuel tables and cut back as neccesary...

Re: running rich

No i had my prom sent to TPIparts.net and they did it for me. They also disabled the egr and smog.

Ok about the o2 sensors...should i have one or 2?

They guy who had the car before me coverted it to a 1 cat car...oneday ill put the duel cats back on but for now i cant. So i only have one oxygen sensor (i thought there was supposed to be 2?)

I cleaned it off with some break cleaner and stuck it back in...maybe i should get a new 1..

Re: running rich

setting it to 30lbs helped alot it smokes alot less but it still runs pretty rich.

But it smoked real bad b4 i put the prom in...so if the problems still there...maybe it is my o2 sensor..
