your car is running lean, this is probably because of a vacuum leak.

replaced what exactly?
vacuum is not a replaceable thing, it's generated by the engine and if you have a gasket leak you'll allow unmetered air to enter and lean it out.

no, there isn't.
you can trace a vacuum leak with a propane can, put some tubing on it and with the car idling blast all around the intake manifold, if it sucks any in the rpm's will jump up and you've found where the leak is.
