    OK.  I'll have to look around for the thing tomorrow after I get up and see what I can find out.  Seems odd that I'd have a sudden huge vacuum leak, unless some hose somewhere suddenly ruptured in a big way.  Will also check the IACV.  

    Read an article on IACV cleaning.  May sound like a stupid question, but, are throttle body cleaner and carb cleaner basically the same thing?   Sounds like they're pretty similar other than that carb cleaner may be a little more potent.

        I take it that they're not the same?  I should be using TB cleaner?

          My understanding is that TB Cleaner is not harsh on Teflon bushings or coated surfaces (anti-icing for throttle shafts) and carb cleaner is. I would probably use  Carb cleaner on it in a pinch.

            Carb cleaner isn't as harsh as everyone thinks. That shit evaporates so damn fast

                  Well, get this; After work I go out to start the car. Starts a little hard and runs a little rough for a few seconds, but then, straightens right out and ran fine all the way home.  Ran like normal yesterday too.  We'll see how she runs today.  Normal idle, and no problems with anything whatsoever.

                  I think I can rule out vacuum leaks and probably a clogged IACV.  Briefly considered that something might have briefly clogged the fuel filter, but, I doubt it would have started at all then.  Still wondering about the TPS, though.  Might be that it's working OK for now, but, could fail again at some point?

                    Does your oil smell like gas?

                      An ICV can act up and still work fine. I would clean in as a preventative measure if anything. My M20 did the same thing. 

                      Good luck

                        Sounds like a plan.  

                        No, my oil does not smell like gas.
