Control Valve #1 Function Question
 

OK, I was wondering about the Control Valve #1, I think, in the system. Under the hood on the drivers side Outboard. When I got my car, the line that goes from the Vac line from the J-Hose area goes to this valve then goes, looks to be the fire wall. That line was plugged off from the J-Hose area with a bolt, and the valve was not in play. Hooked it up, not sure if it made a diff. There is an adjustible set screw on the top ov the valve. What dose thsi do? THe 2 Vacc canisters on the Fresh air fan assembly have no vac, could this go to this? Have no clue. Thanks Mike

Everything you ever wanted to know about the EVAP system!

Thanks, More than likely the CVI is bad. I have noticed the Idle running a little on the off side. That sould take care of that problem. Now just gotta find one that works. Is it a 100% Important part? Can I get buy with it plugged? Thanks Mike
