I swapped a B18B1 with a P75 ecu into my 92 civic lx

Everything is fine, the car can run, except that the motor runs extremely rich...
we found out that I have two map sensors... and the two connectors seems to be working......
could it be what makes the engine running rich ??? or could it be vacuums plugged at wrong locations ???

 

no ideas ?

 

only one should be working and it should be the one on the throttle body because it has a specfic location that it gets its reading from. but i wouldnt think that it would make it run rich

 

what engine harness did you use? is the vacuum line hooked up on the firewall map sensor? is your tps hooked up?
