I need help Honda guys. I just did a b18c jdm gsr swap into a 98 civic ex and now my car splutters at mid rpm range and my tachometer is not working. I used the ex harness and rewired it to obd1. I also used a jumper harness obd2a to obd1. What I had to do was cut and rewire plugs; injectors, distrubitor, IAT, alternator, and extend my o2 sensor.

I have a cell light and it is reading code 4 which is the ckp sensor, but I am running a chipped p28 ecu. And code 10 which is the IAT.

I checked just incase I had my TPS switched around with my MAP sensor and I actually had them in the right location.

Please help, I searched but had no luck. Another thing that I was wondering is if it is possible that an injector in the wrong firing order will cause this.

Vehicle is drivable but it will have a fuel cut off after 3000rpm if you floor it.

Please help!!!!

 

i had the same problem.. redline at 3k rpms.. i had to rewire a new harness.. i couldnt figure it out.. sorry.. but as for the ckp sensor.. use this trick..
