Fixed a Secondary System Vacuum Leak

Another tip: I don't disconnect the throttle cable.

I agree. Good tip. I put a padded cloth (a folded towel work great) on the driver's side of the windshield, covering the wiper arm. Then you can just flip the plenum over and set it upside-down.

Ahh, I see that hose you mean. Yeah, on a '90 that comes out on the driver's side. Interesting about the throttle cables. The windshield is what I lean on though, when I'm standing on a tire and the alternator and trying to reach whatever the heck had me pulling it off in the first place.

If our cars didn't have clamshell hoods, I'd really have a hard time of it.

Jim,

I rest the plenum up by the front of the wheel well. Like Bob I use the windshield for support. Also, I disconnect that hard line at the throttle body and then just slip it on fitting as one of the last things before I button things up. I put some sillicone sealer at bottom
of that hardline and the one next to it. In fact, I put a small coating of clear silicone gasket around all vacuum line junctions that usually have a tendency to pop out. Just a thin film to seal and hold in position.

Great Job guys, Now that you mastered the plenum pull, time to step up to doing some P&P work.

It takes all of 2 minutes at most? Then you can get the plenum completely out of the way.

Jeff,

Where do you disconnect it? And does it affect the setting of the throttle position sensor?

Thanks

It does not affect the tps sensor. You undo the two clips that hold it onto the plenum, then hold the TB blades open either with something from the front of the motor, or the side and slide the cable off the linkage, and there is a retaining tab to keep the black plastic piece from sliding out as well.

Thanks Jeff, I will try that next time. It will make cleaning the plenum a lot easier as well.

That's what I did this weekend, three times..... don't ask

Anyway, its as easy as Jeff describes. I used a small screwdriver in from the side to hold the cable wheel in place, and then rotate the plastic piece out of the way and bingo out comes the cable end. I will add that the cable is held into the metal housing via clip, if you come in from the front of the housing with a very small screwdriver you can push in the clip (round hole about 1/8" dia) and the cable will slide loose. It's a fast and easy removal, once you do it. (took longer to type this up than removing the cable would take.
