    When I start my car in the morning or after it been sitting all day and is cold the v-tec doesn't work. As soon as the motor starts warms up up can here that the v-tec starts to kick in. After the motor is at normal operating temp it works fine.
    Any Ideas? Let me know

    Not quite...

    The ECU uses several parameters to determine when to engage VTEC. Engine speed, vehicle speed, coolant temp, and oil pressure. Engine speed depends on the engine, but vehicle speed is 20 MPH, coolant temp is 160°, and oil pressure is 40 PSI.

    When the engine is cold, you shouldn't rev it above 3000 RPM. Or, you can and eventually blow your motor. It's your call.

    :withstupid: that really is the best advice for ANY engine...

    when it's cold why do you need to rev your engine all the way out anyway?

    VTEC will not engage when the engine is cold

    i thought it was cuz the solenoid was frozen....

    like sometimes door popper solenoids freeze up when its cold, and you gotta let 'em thaw 'fore you can pop your door

    yeah your solenoid is frozen, next time you start your car and its cold, just get in and rev it to 8k for about 5 mins. That should fix your vtec issues. :ph34r:

    Just don't be an asshat. Let your car warm up. It's good for it.

    Okay heres what happened. Normally i do let it warm up and thats why i never noticed before. but last week i was late for work, so i got in my car and left right away. thats when i noticed that the v-tec wasn't working until it warmed up. so after work i did the same thing. Thats when i posted my question cause i was just wondering why. For the people that answered my question, I thank.
