I recently read on another post a similar problem and the solution was switching the wires on the coolant temp switch. I did this and the high idle has been fixed, but now I've noticed it has an intermitent grumble when in the warm up phase, which wasn't there before.
I think I got most of the hoses. The hose to the brake booster seems fine, but the 90 deg fitting that connects the hose to the booster is the thing that plays. It's one of those one way push fittings, which i've taken out before and the only way seems to be cutting. Is there a technique you know of that won't damage the booster?
Also, I should note I noticed this problem after doing my head gasket. All of the hoses around the intake are solid and new. Can the connector on the coolant temp sensor be put on backwards or is it a one way fit?
And the o-rings to the injectors are new too.
