RB25DET rich idle

[doriftosil13]

Hey guys im new to the board and i had a question for you guys. I just got a RB25DET and put it in and followed the diagram to wire it into a S13. ok when the car is cold and i start it then it will idle fine but once it gets warmer the engine will sound like its missing really bad and it will die and will not idle anymore. even with that problem when the car is warm i could open the throttle up and it will rev but sound like its missing revving up. I was thinking it could be the MAF or maybe a coolant temp sensor. any thought on what this could be? I checked my wiring like 10 times and its all good so i was thinking it was a sensor of some sort. any help would be appreciated.

Vacuum leak more than likely. Check your AICV as well.

well i have no vacuum leaks and the weird thing is that when i run the car with the MAF disconnected it runs fine for the most part. it wont idle either way but revving it with it off is alot smoother and doesnt seem to miss giving it wont revvpast 4k rpm but then i plug it in and it revs high again and misses the whole time.
