Well, last night's shade tree workshop session went well - until it started raining. [iffy forecast for this evening too]

I found that both hoses [upstream and downstream] on the idle air valve seem 'porous', with numerous small defects. [no way to judge the aggregate area].

The original hoses had one clamp, a spring clamp where it connects to the manifold [by the cold start valve] but there does not seem to be any way to get pliers on it. Since it's a spring clamp, can the hose just be forced into place?

Should the other connections for the idle valve hoses have clamps?

Since I have everything apart anyway, I'm also going to replace all the injector seals [insulators, seals & O rings].
