Hey George thanks for the reply. I looked at the plugs and noticed the one against the firewall and closest to the driver. Its plug wire slips on and off the plug easily and doesnt snap onto the plug like the other wires do. But if there was a problem with the valves wouldn't the check engine light come on?

I have a 1992 es300 and its missing. It doesn't have a check engine light on and its not blowing smoke out the exhuast. A guy told me its a valve but wouldn't the check engine light be on? What are the other possibilities could I rule out? Thanks for the help!
