I found a source for some NOS 2.0L cold start valve. They will be reasonably priced at around $120 shipped, not the $200+ prices on Ebay. I will take about a month to get them because of the location. Let me know if you want one. Going to order at the first of next week.

Unless you live in a location at or below freezing, the thermoswitch/TTS (temp driven ground for the CSV electrical circuit) will not activate and the CSV is never called into service to provide fuel. They become a problem when it leaks though (too rich) even in warm climates. Suggest that these are only needed by the cold climate folks and everyone else should just delete or disconnect them.
TS/TTS values (from Anders): 311 906 161 : -12 to -18 deg. C / 10 to 0 deg. F 311 906 161 A : 0 to -10 deg. C / 32 to 14 deg. F 311 906 161 B : -2 to -8 deg. C / 28 to 18 deg. F 311 906 161 C : -6 to -14 deg. C / 21 to 7 deg. F |

F 311 906 161 C : -6 to -14 deg. C / 21 to 7 deg. F Fully agree on this. In MD temps do get to freezing and below during 3 months out of the year. I have started my car below freezing temps and while it initially starts with a low idle it quickly raises to above 1500 RPMs as part of the normal startup of FI. As Jeff stated the less items that can cause problems in the FI the better. I believe another member on here as well as others have removed the CSV, decel Val, and there was one more. My car currently has a disabled CSV and no Decel Val. It starts and runs great without these. |
