Well, When I am driving my car, and when I punch it and I am in VTEC, it will be in VTEC, then kinda shit out. I have enough oil in the engine. It will have a nasty noise to it, like it is in VTEC then like comes out when I throttle ALL the way down, it only does this sometimes. Is my VTEC solenoid bad? I mean the part is 15 years old. Is there anyway I can check the VTEC solenoid to see if it is bad? What else would cause this to happen? Has anyone else had the problem?
