    ever since i got a JDM b16 swap The code readers cant read my ECU. The engine light is always on but i cant do nothing about it. My ecu is a p30. How can i fix this problem if i dont even know where to start. When i ride my car for awhile it hesitates to gain more speed, and when i shut the car off and start it back the hesitation is gone but it comes back after a few mins. And when i make a complete stop the car shuts off automaticlly unless i put it in Neutral then it doesnt shut off.
    I cleaned the injectors, got new spark plugs and wires, new distributor, I cleaned the vtec solinode, I changed the Map sensor, I checked the timing, but i think it has to be a fuel thing, the spark is fine. Can it be the fuel filter? Can i exchange a civic DX fuel rail and injectors into a B-series engine?

    what car is it in and do you know how to count the codes yourself theres a 2 wire plug on the passenger side down around behind the kick panel area it should be blue i think. it will have just 2 wires going to it jump those 2 wires together with a paper clip or something then count the check engine light it will be flashing long pulse =10s fast pulse =1s

    It's in a 97 civic dx. you mean take the kick panel out where the ecu is and there should be a blue wire connected to my ecu? You lost me when your talking about the paper clip and counting the codes

    it's obd1, and the codes cannot be read, when i went for an inspection the guy told me that my car has no life lol. He said that when he pluged the machine into my ecu it read nothing. The guy who did my swap must of really messed up my wiring, he customized my wiring to make my car run.
