hello I have a 1938 Oldsmobile business coupe with a 6.0 with flex fuel injectors on it and a return less fuel rail I'm new to this .
I was getting lean codes bank one and bank two during idle and it would set a code when the place set up my flex fuel injectors they only set the flow rate to 36.5 and didn't change the injector data.
i got the injector data off of a 04 tahoe 5.3 flex fuel that's what the injectors came off of but everything I have read the fuel pressure on the flex fuel is 33@50 lbs. so i put in the 33 @50lbs in the unit conversion tool.
it smells like its running rich
and I'm trying to get it to hold first gear when stand on it
