So I recently purchased an 89 corolla sedan with a 4agte swap. Now I'm not new to the boost/swap world. I've had many dsm's. Anyway I'm new to yotas they are a different animal all together. Keep in mind I've got the orange top injectors, upgraded fuel pump, running 10psi on a t25.

Problems as follows.

 

1. Speedo tach not working

2. Running very very rich (blows black smoke and backfires)

3. Bucking at mid throttle

4.engine codes I pulled:

-12-

-21-

-41-

-42-

-43-

 

Any help in these issues is greatly apptrceated..if i have to i will go with an ems. But if these issues can be fixed with simple solutions I'm all ears..I've done extensive searches on google ..I've found some helpful tips but nothing in depth to what I'm looking for.
