thanks that did the trick now the cars starts but it idles at about 4000 to 1000 back to 3000 to 1000 and so fourth. Also we noticed that the readiator hose doesnt build up any pressure or get hot at all would that have something to do with the fan switch? But besides that it rums fine if you try to drive it, it bogs out like it has a vaccum leak some where.
