Throttle switch

[Al]

I have been having problems with the first start of the day. I won’t start on the first try, runs a few seconds and dies. Then it takes a long cranking period before it finally fires, acting like it’s too rich.

I pulled the codes and only got one, 2344 or air leak. Valve cover. I fixed that this weekend and erased the code. 

This morning same thing but no codes. Ok, I fixed the air leak. 

I took out my Bentley, my home made VW1501 and checked the idle and full throttle switches.
The idle shows 0 volts when closed and no battery  voltage when I open the throttle.

Full throttle closed shows approximate battery voltage and 0 volts when completely open.

Looks like I need a new throttle switch. I checked the FA and it only shows the upper (full throttle) switch. Part number 026-133-093D. Are the two switches on the cable assembly?

I pulled the codes again and no faults. (4-4-4-4)
