ive had my check engine light on ever since i took the dash off replaced the heater core and put the dash back on. i did the pin trick or whatever it is to see the check engine light blink and i got 21. its the vtec solenoid..i changed it out with a new one but the check engine light is still on. ive driven on it for awhile and disconnected the battery and the lights still on...any ideas would be appreciated! its a d16z6 on p28
