we are putting a jdm b16a (obd 0) into a 90 civic std. The motor is in and the car will start but we have a code 4 and the engine is runnig very poorly. Wondering if any one can help us rid the code.

 

Code 4 is the crank position sensor.

 

yea i know what code 4 is, just wondering if anyone has had this problem before and what they did to fix it!!!

 

check your wiring around the distributor and check the timing of the distrubitor. Loosen the bolts that hold the distributor in place and have somebody rev the motor while you are turningt he distributor clockwise and counterclockwise until it sounds like its running good.

 

we checked every wire from origin to the ecu and they all go the the correct pin. Thanks Slavko we will try dist. timing but i truly dont think that is it. Any body else with some ideas
