New injectors, running rich. Howell fuel inject.

Error code 45, running rich, check engine coming on and off.
Fairly new o2 sensor also.

Anyone go through this with the Howell setup?

Thanks

Is this a new installation or just new injectors? If this is just replacement, is it possible that the injectors are the ones for a big block (454) rather than ones meant for the smaller engines (4.3,5.7)? The bigger injectors will certainly run rich as the injector pulse can't be shortened enough to keep the fuel burn within program parameters. God bless.
