Wow, just learned something new or just forgotten about the TTV.

At one point I replaced all my vacuum lines except the really big fat one on the back of the engine that you have to do a partial engine drop to get at.

Once all the really minor leaks were cleared up it sort of magnified anything else wrong and I had to readjust things like the fuel air mixture again.

Just a heads up for anyone trying to fix things only to have things running worse afterwords, it's maybe not your fault, just more adjustments ahead as you woke a sleeping dog.
