I just recently bought a b18c JDM type-r and swaped it into my 96ls.

I ran direct connections to the Vtec solenoid and knock sensor. The engine came with a ECU and everything is connected properly. I believe its a p72 or p98

The car is ground and no CEL is on.

Oil is full and there are no dents on the pan.

Vtec worked initally when I first ran the car. But it comes and goes everytime i stop and start the car. It is warm but my tempature guage seems to not work correctly. I unplugged the solenoid while the car was running and the CEL came on. I tested the solenoid by running 12v to it and it clicked. I am checking if the solenoid is clogged tomorrow but other then that I have no idea what could be my problem.

Help!

 

The engine came with an APEX grounding kit. I did not use it in the swap and the car runs fine. Would that kit be my problem?

 

Try changing out your thermostat. The ecu is reading the temp as low so it wont engage into vtec.

 

Well I took the solenoid off and cleaned it out. Bought a new Thermastat but vtec was working all day when the car was warm. I guess it fixed itself over night.

that is just a capacitor and has nothing to do with the workings of your car
