Please, i have 5 sets of injectors but i have no idea what the flow rates are.
Car runs rich and i’ve been advised to look at the injectors. Currently i’m running the KEIHIN 5LFK injectors.

Car is 96 accord F22B1 engine and everything seems to work fine except that the mileage is bad. Done all the electrical tests and they’re good. But car shoots black smoke when revved.

The injectors are
1. KEIHIN 5LFK
2. KEIHIN 5FLV
3. IPT 4008
4. IPT 4109
5. KEIHIN 6KFA

I’ld appreciate the guidance on their flow rates and which to swap to.
Thanks.
