Swapped a k20a2 into my eg recently. Second motor, first one engaged vtec always no problem. I used the vtec solenoid from the first motor on this one and now it isn't always engaging. Earlier I pulled both plugs off the solenoid and plugged them back in and vtec engaged 3 or 4 times and now it won't again. When datalogging, it shows vtec engaging but it doesn't kick or change exhaust note like it did the couple times it did work. I'm thinking a bad vtec solenoid?
