I have the same question about the lb-7 I got a bad #4 injector according to efilive balance rates so I got a new injector and replaced it and the balance rates are still the same and still has a hard ( extended) start same as before I replaced the second injector from the front on the drivers side I'm wondering if it is the fourth in fireing order which would be number 8.

Would like some info on this before I tear into it again
