Starts good, cold idle bad, warm idle good

[rick@brubakerbox.com (Rick Alexander)]

1. This goes to the upshift switch then on to the charcoal canister in the
left fender.

2. This goes to the tee in the brake booster hose then on to the climate
controls.

3. This one goes to the intake preheater control down below the battery or
above the horn depending on your point of view.

4. I can't remember, something about oldsheimers. Your owners manual will
say.

Hope this helps.
