the question show you have not studied the FI system, and are trying to equate it to others you have known. Read the manual on it. There is no O2 sensor on a 1977. Here is a pdf you should look over.

hey, VW FI of this generation didn't use an O2 sensor. It measures the air flow and gives it fuel based on that. As for the cold start valve, it us mounted directly to the plenum. The pill looking thing that the intake runners extend from.

I see you've posted a bit in the Vanagon forum. The stock bay fuel injection systems did not use an O2 sensor, except for the '79 California emissions setup; it did.

It was never meant as an insult. It is just that if you want to get involved with it, you will need to spend some time learning how it works. It isn't hard but if you approach it with what do I do next, the different ways people think here in the bay forum will drag you all over the marsh. Sometimes this place is like 5 blind men trying to describe an elephant. You know the story - one guy says it was like a tree trunk, the next says it was like ole parchment paper that moved, another says it was like a rope with a paint brush on the end, another says it was like the side of an old weathered barn while one guy asks why his experience was so different being that it was like a firehose that breathed and smelled of peanuts.
