Check your oil levels, make sure the car is at normal operating temp before trying to hit vtec.
Make sure everything is plugged in: vtec oil pressure switch & vtec cyl
i just did an oil change today and i put a new thermostat in last sunday. temp and oil press are fine. i have checking all plug ins for the solenoid. im not thorwing any codes either. it dont make sense
