Hey I'm 16 and this is my first build and i'm having a lot of trouble with it, there is probably a simple answere to my troubles but im not seeing it, any help is welcome
This is a KA24DE s14 engine that I swapped into a 92 240sx s13 body, The engine starts up and runs for 5 to 10 seconds, but when the ECM tries to take over the engine bogs down and dies. What i mean by take over is when it finishes the initial start and then tries to idle down something with the ECM make the engine die on me, I've been troubleshooting for weeks now and can't figure it out, I have the consult port hooked up and tried to figure out whats wrong but I'm not having much luck. The MAF is new and works, I tested the Idle Air Control Valve and seems to work and the Throttle Position Sensor is getting the proper reading.
Here is a digital reading from the consult port I recorded, if anybody see's anything that i don't it would be a great help.
