I just had my ECU chipped to have the VTEC kick in at 4800 RPMs. When I reach this, the VTEC does kick in, but the check engine light goes on. However, when I turn the car off and start it again, the check engine light is gone.
When my VTEC kicks in, it seems like there is a loss of power. It sounds loud but the car instantly stops accelerating as quickly as it did before the VTEC kicked in. Could the problem be a bad VTEC solenoid?? If it is all in my head and the VTEC is fine, what is the check engine light for??
