"
I just did the same job over the weekend."
Ugh!
This was my third time in the last month.
First it was a visible broken line and a vaulty ICV (P0506). Replaced vacuum line and ICV and drove for 200 miles with clear codes and no CEL .
Then I replaced the electric change over valve, because it failed 2 weeks later.
Drove another 250 miles and then P0410 and P1411 returned.
Oh joy!
Went to the Pelican and ordered new vacuum chamber reservior, new change over valve, new check valves and new rubber hose connections. Luckily the air pump is working strong with no dying noises.
Word of advice:
You can be cheap, but what is your time worth ? Spend an extra hour or two checking all the components before you put it back together, or just replace them all at once. It's hot in that engine bay. Those plastic and rubber parts have had nearly 20 years to vulcanize.
The good news:
I've become very fast after three visits to the SAI system.
