Ok so i picked up a 93 eg coupe with b18a1 and jdm head the other day, and the cel is on and throwing 3 and 6 codes.
It doesnt like to be cold started has a hard time staying running
and when i start it, it will start and idle low like it wants to shut off then go back up after its warmed up

3 is MAP sensor

and 6 is ECT (engine coolant temp) sensor.

so a buddy gave me a new MAP sensor and replaced it, unhooked the battery for awhile to reset the code.
still came on as map sensor

and the ect connector was still from a d series so i swapped the connector wired it up and still has code 6

and will still run like before.

anybody know what to do?
