	 Yes I have heard of this problem and every time it was the master
cylinder.To tset remove m-cyl from booster two 13mm bolts and try to
turn the aluminum piston sticking out the back of the m-cyl DO NOT USE
TOOLS. Use your fingers only use of pliers will scratch surface and will
damage m-cyl.The piston should be able to turn with your fingers if it
is tight it probably needs replaced.
	This condition as you describe it "car bogging down intermittently on a
warm day" is kind of a problem on 5k's and 100's/200's.
