Accepted Answer
OK, normally a searching idle is caused by a vaccum leak. I would start by spraying carb cleaner around the intake manifold where it bolts to the heads. If the idle increases or smooths out, then you have a vaccum leak and the gaskets will need to be replaced. Try this test and let me know the outcome and we can take it from there.

Yes, that is fine. We may have to play around a bit to see if we can find the problem. Let me know the results and we can take it from there!
