There are two or three heatshields that are bolted to the underside of the body above the exhaust pipes next to the transmission, unless someone removed them.

Not the best pictures, but it's what I could find.

 

Ohhh yes they are removed already. I saved a set from a doner car I used a few years back tho...


Doner car was slammed...


So my airpump is removed, but not this thing:

Where boost pressure sensor was hooked up to...



I want to start cleaning up odds and ends so I picked up a block off plate set awhile back, but.... the boost pressure sensor is hooked up to the nipple I'm pointing @. I'm thinking just "T" these two together...???

Can I tee off boost pressure sensor from this thing (recirculating valve...??)

 

I ran a line from a nipple right off the UIM (or lim can't really remember) but it's right under the bac if I remember correctly. Also the thing you're pointing at is the bypass valve. I don't remember stock vacuum routing but I think that your sensor is hooked up right? Unless that valve has tworked nipples? It's been awhile since I was stock lol

 

The air pump has been removed from the day I owned the car. A bunch of stuff was capped and unlpugged in it's area. The guys who worked on the doner car are a well known rotary shop so I'd assume the air pump was removed properly. The exhaust is a 3" straight pipe to two Flow Masters.

 

All is done and idle is back to lope'ing again. I'm thinking it HAS TO be from the boost pressure sensor coming off of a different reference port or the Air Pump Mechanism now being removed and blocked off. Ughhhhhh The idle drove me crazy for quite some time being I'm still the kid who can not sit still for tooo long and figure things out, and then... I finally did get it. I hope it's easier this time around.
