Wasn't California recently considering moving the date up to something like 1979 for smog? Sorry for the "thread jack"...

It's been a while since I looked into this. But there is something worth mentioning. Now that mornings are quite cold, high 30a low 40s, the car has been starting at the first attempt. It's an indication that the CSV is actually spraying the extra fuel (I also confirmed it with the injector in the jar test the other day on the cold morning). Just as starting fluid in a warmer day will make it start right up, the CSV helps. But this is just masking the issue. Some of you have mentioned that you entirely removed the CSV, and have no problem starting. One thing I would like to throw out there for consideration that I was told is vapor lock. What do you guys think about this theory? Anyways, there is not much more time left for me to drive this season. Car will probably go into storage pretty soon here. Maybe it will fix itself over the winter and the problem will be gone in the spring, no?

I was one that said I had removed my CSV, and the engine does start okay, but is slow on days when the engine bay is cold.  Pretty sure it's all about vaporization.  If the morning is foggy and it's cold out, the best starting routine is to crank it for a few revolutions, let it sit for about 10 seconds, then start it.  Otherwise I do get extended cranking time.

 

On a cold morning, but with sun on the hood of the car, it will start right up.  The only decent explanation, to me, is cold metal hindering fuel vaporization.  I also mentioned holding the throttle open while cranking as a way to get it to start faster, hence the discussion about clear-flood mode.  "Vapor lock" doesn't happen on the EFI cars, they're high pressure systems.  Plus the fact that vapor lock is a heat problem, and yous is a cold one.

 

I can understand wanting a quick start like a modern car.  Just not sure it's easy to get to.  Note also, that the fuel manufacturers change the formulation in the winter time for faster vaporization.  This may be applying in your case.  New fuel blends start flowing in September, apparently.  About time for more "hot start problem" posts.

 

Here's some articles.  It's a fun topic.  Couldn't find any Iowa specific pages.
