How you can test the Vtec Solenoid Hook Up valve, because i noticed my car has loss power in high rpm's and today i follow the instructions to test the Wiring Harness of the Solenoid and the book says BETWEEN THE WIRING HARNESS CONECTOR AND BODY GROUND IT NOT SHOULD BE CONTINUITY BUT IN MY CAR THE RESULT ITS NOT THE SAME ALL THE OTHERS TESTS ARE FINE BUT THIS ONE IS THE ONLY BAD, you think this can affect the performance? if someone knows about Fuel Injection and Vtec Systems help me please Thanks
