There should only be one hose that needs to be connected, that hose connects to the valve cover. Check out this photo at my old website:

It seems you can turn the valves, how do you know where they should be turned to?

One got turned a bit when I installed my CAI, probably soemthing less than 180 degrees, would this make any difference?

the second diagram is AWESOME ... and also avail from autozone repair website, but its hard to find. there is a post on this forum by flora regarding it. its not colorized (the poster colorized it here). it's also likely higher resolution and i like it more, but this picture is still awesome. the first diagram is a neat thing, but doesn't help when you're trying to connect all those vacuum lines on the manifold. lol

Great post Sir,

This is great help to find the EGR.

The 626 is my wifies car I have multiple BGs so they are just a bit different. OBD III on the 98, my BGs are OBD II.

This care is a great cruising vehicle, throws codes often but never has been a seriously ill vehicle.

It's always an o2 sensor, air issue. I'm going to pull the Egr to clean, see if that does the trick.

I once had a 351M in a 78 Tbird, that was forever stopping up.

I have been chasing a P0443 error (EVAP System) for a while. Finally gave up and went to have it tested at TUNEX. They were very helpful and were able to figure out my problem and fix it in an hour. The short story answer is that the electrical connector to the Purge valve was swapped with another connector under the air box.

What I did find in my attempts was that the engine changed in 1998-2002. The vacuum diagram posted here is for earlier models. I have attached the printout given to me by TUNEX. I hope it helps.

I had a mechanic solve this one for me. It is probably a vacuum leak from the throttle body. The factory gasket wasn't sealing well enough even though it was new. He made a custom gasket out of thicker material that has worked like a champ for over a year.

thanks for sharing.

I have a leak somewhere after doing a valve cover gasket and have removed the manifold 5 times, just 3 yesterday and still could not find the air leak. it is coming from the throttle body area but since i bought a new felt pro gasket, i thought it should not be the problem and blamed the canisters which i check is in good condition.

do you happen to know if he used some paper/metal gasket or just rtv?

Thanks.
