Re: Bad spark plugs or wires
Bad wires or bad plugs will not prevent Vtec from engaging.
Here are some known causes from my experience on what cause Vtec not to engage.
1. Faulty Speedo plug - because it sits so low your speedo plug may be corroded and causing it to give a bad reading which in turn causes you to loose Vtec function however your speedo will still work.
2. Ground on your vtec solenoid - double check where it is grounded and ensure a good connnetion.
3. Loose connector on the Vtec oil pressure switch
4. Low oil
that is all i can think of right now.
