94SRUNNER - I was thinking that because the tube was clogged, it may have been covering up an actual low flow problem, since it did not have a reference. I am planning on systematically checking the system as time allows, starting with the modulator.
Kernal - You are correct. Reading this thread helped me understand what the line did and why others were getting the 0402 code. I thought I would check mine just to see if it was plugged and it was. I was able to push a small straightened out paper clip, followed by a larger one that just fit the tube. After this my 0401 code showed up.
alia176 - I will do a search for that thread, as I have a hard time getting a few fingers in the area around the VSV! If I an move it to a better location, boy howdy I will, plus understanding this system seems paramount to being able to fix it properly!
Thanks guys!
