Today I capped off the two lines that run from the throttle body to the VSV modulator. I used a pretty slick tip from our own Beowulf. IIRC he was the one that mentioned to place a "BB" (as in BB gun) into the vacuum line as a sly way to pass visual inspection with a LT MAF. The fit perfectly in the lines.

I also placed a 3.9K ohm resistor (same one Gotmud used) in the EGR temp plug and cleared the codes via SGII.

So far, so good. No P0401's, it idles and drives like it should. Not enough data to tell if the was an MPG +/- yet.

Does anyone know where the EGR pipe leads to? It seems to go down behind the motor somewhere and eventually pull exhaust up to the intake. I ask because it seems like even though the vac lines are disconnected/plugged, the hot exhaust should still be able to creep up through the EGR and get sucked into the intake.

Am I wrong? I know the lovely boyo and a few other people were wondering the same thing, but I didn't see anyone give them a clear answer.

I'm trying to read more about the EGR system but I only have the electronic FSM and I haven't deciphered the file labels yet so it's been slow going trying to find relevant pages.

Thanks!
