hey guys im new to honda world and ive searched everywhere and im just not getting it. i have a 96 civic with a obd0 1st gen jdm b16a with a 94-95 gsr ecu obd1. i bought the car in december and i knew nothing about the vtec or hearing when it kicks in. well it never worked until about a month ago it started working out of know where... now it stop working again. i do have cel and i checked and its code 21. i tested the selenoid and it does work. clicks when i hook power up to it. read a guy put a toggle switch for it so i tried it and vtec works when i flick the switch at 5200 rpms. what could be my problem? i even ran a wire from seloniod right to the a4 pin on ecu to see if i had a bad wire and still didnt work. please any help would be great.
