[RESOLVED] Know what this is? purge control valve

[1gDSM4g63]

My car wideband reading are not stable, no boost, and at random times it dies in 3 or 4 gear while under throttle. I done compression test and leak down test. They both check out fine. However, when I do a boost leak test I cannot get any air pressure. Somewhere there is a huge leak but I cannot find. All intercooler piping and boost controller vacuum lines are connected. This might be the cause but I have no idea why it is. When I found out under the battery rack 1 of the 4 openings was open.

That is your purge control valve. Now the next question is are you running smog if no the very front and back lines on the T/B have to be capped. If yes follow the under hood hose diagram and hook them up accordanly

Don't understand. Is one a the four outlets supposedly to be open?

If I'm not mistaken it is under your battery. Here is a diagram for you.Hope this helps

And for the removal of the unnecessary ones, are listed below. From mild to wild. For the race version (last picture it is hard to keep running on cold starts)

And after looking at my engine bay pics, it looks like all 4 should be connected.

Only 3 lines seem to be used if you look at my first diagram.

I'm unsure if there is a difference in the 1G/2G uses but just keep that in mind. As I'm to lazy to do the research

EDIT: Only 3 lines seem to be used if you look at my first diagram. The 2G must use an extra line somewhere along the line.

Well, I missed that it was a 1g at first, but even after looking at the 1g user manual, it shows 4 lines. I believe the one that doesn't have a line attached but has an arrow coming out goes to the intake pipe.

Very true! It's so much cleaner without it. But if your state requires inspection (as mine does), then you can't.

Luckily, I can apply for emissions exemption if I drive my car under 5k miles. My engine bay is so much cleaner now!

Same here, I have a huge box of $hit that I took out . I'm going to check out the Non-Cruise Control Throttle cable next.

No worries here in IN, you should see some of the stuff that is driven around.

Sometimes I think The Fast & The Furious was filmed and thought of here in the central part of IN.
