Default Problems swaping d16y8 on an eg4

Hello, Im swapping a d16y8 into my eg4 obd0 using the obd0 wiring, but im having some issues now with the wiring I think.

I made the dpfi to mpfi conversion following this guide, the only difference is that in my ECU, c1 was Blue green and c2 was Blue yellow I moved it to b10 and b12 like in the guide and add two new cables from this pins to the distributor (y/g Ign input signal and b/g crank position output)

Then I wired the y8 distributor, following the next post matching the obd0 with the obd2a:

I used a obd0 to obd1 harness and a p28 and I wired the 02 sensor and the vtec

My problem now is that when I start the engine, if I don't hit the accelerator, the engine start and stop. And if I open full throttle, the engine continue running but with two explosions every two seconds and dont go up of 1000 rev at full throttle.

Any Idea of what im missing? Thanks in advice!!

Ok, I have the engine running now but with a problem

The problem was that on the dpfi to mpfi conversion I didnt changed the cables of the TPS and I put incorrectly the connector of the IACV, after this, the engine start fine.

The problem now, I checked with the engine light and now I have a MAP sensor fail, the car not run fin at low RPM.

My car has originally the map sensor on the firewall, I move the connector to the MAP sensor in the Y8 intake, Is any modification on the wiring needed?
