POE

The head I used to do the Mini me swap (D16z6 head) was sitting in the car for about 7 months without running, well my vtec worked in my car for about 2 months, then it started throwing code 21 vtec not working. Well i check all my wires and made sure they were plug in, what else could i do to check it? Someone said maybe that the soleniod can mabye become clogged and that needs to be taken out and cleaned, is that mabye a factor sence my car head was sitting unused for 7 months?

Yes, you should try cleaning the screen in the solenoid before purchasing a new one.
