I have right now at my work a 99 Civic Si with 55k on the odometer. Bad thing is it has a JDm swap, the motor code is B16A. The head is stamped 96. The problems we are having is the motor was thrown in and not really hooked up. On the fuel injector wire harness there is a plug not hooked up to anything. Tim (Timmay on H-T) said it probably goes to the intake temp guage or whatever. There is also another plug coming from below the motor that isn't hooked to anything and when we lifted the car off the ground we couldn't see where it should be hooked into or where it came from. I will get pics later. The main problem is the motor will rev fine and VTEC engages normal, but it hits rev limiter at 6800rpm. What would cause this and ow can I fix it. The ECU is just fine, P2T right? The last problem is when the brakes are applied all the lights come on, like the front turn signals and the rear turn signals. The lights also come on inside the car when the brakes are applied. I know I work at a Honda dealership but we can't seem to figure these simple problems out. Please help me and my dealership!!! of Pocatello

 

Hmm, do you have any CEL's. Only thing I can really recommend is to check the codes at this point and go from there...

Get the codes and keep us posted.

 

CEL's??

 

Check Engine Light

 

oh, sorry, no there are no check eng lights on in the car.

 

The plug you are referring to that is probably not connected is the IAT (Intake Air Temperature) sensor.

It's usually a black or white sensor on the intake manifold near the fuel rail.
