There are two pic's showing where to spray the Carburetor Cleaner into the Throttle Body.  Be a little creative and spray SHORT SQUIRTS from different angles to try and cover all sides of the Throttle Body.  Remember, if you spray too much cleaner at one time, the engine will stall.  You will want the engine to run at a fast idle, NOT RACING.  Let the engine recover after each squirt.  I am wondering just how many Throttle Bodies might have been replaced just because they were dirty.  I don't know what they are like inside (or how much they cost) but I guess that they have some passages that can get plugged up with dirt that gets past the air filter.  My 1988 Plymouth V-6 had 180K on it with no problem with the throttle body.  But then I did keep it clean.  I also posted a couple of pic's of a battery disconnect that I installed.  When the vehicle is not in use, I disconnect the batteries so that if one were to go bad, it would not discharge the other battery.  I don't think that it is a good practice to leave two batteries paralleled without a charge being placed on them.  I hope that I did not get too basic but there may be some owners out there that are trying to learn to care for their units.  Now, about my front tire separation.

Bob, I don't know if this will fix your problem or not, but I would try something simple first.  I had problems with the "check engine light" coming on.  The problem was dirt clogging up ports inside of the Throttle Body Assembly.  Before I would spend $600 I would try a $2 squirt (sometimes it takes several treatments) to insure that something did not get clogged up while the vehicle was sitting.  I know what the dealer told you but I would also check that the Throttle Position Sensor was giving the computer the proper information.  It tells the computer how far down you have the accelerator pushed down.  And that could be the "Loss Of Calibration" that you were told about.  With the unit sitting over the winter, you could have developed some contact problems on the Sensor.  If this was part of the problem just pushing the accelerator pedal down XX number of times might help a little.  I don't know if you would have easy access to the TPS so that you might give it a squirt of cleaner.  Just be careful with what ever you do.
