If you mean 0.9 lambda then that is not that rich !!
If it is truly rich, you have at least one or more of the following problems...
1) fuel pressure too high
2) Injectors are not fit for purpose
3) cam overlap causing low manifold pressure
4) sequential injection - injectors in wrong firing order
yeah AFR , target is 13.5 ish , as i lower inj time the afr rises from about 9 to 10 , but as i go lower on inj time ,the car cuts out ?
