Just swapped the head on my brothers h22a to a port and polished head.
Got everything hooked up and the ecu is throwing a map sensor error! I checked the map sensor and even tried replacing it with 2 other sensors. Still throwing the code. I could have the wrong plug in, but im pretty sure that it is right. The h22 is in an integra, running a jdm p13 ecu. Let me know if u have any suggestions! Thanks a lot

 

u have the right plug going into the harness? the tps and map use the same kind of plug to them

 

Most likely have your cam timing off bleeding off compression back into the intake manifold. Do you hear an air leak at idle? I had the same problem when I first put my built head back on!
