Answer
David: When it the last time you did a good tune up on the car? If the tune up does not fix this, then have your car coded, AutoZone will do this for free. It will show if you have any sensor(s) out and then get them fixed. Or one could be getting weak. Another thing to look at would be an vacuum leak someplace. How old is your transmission fluid, have that changed and the filter might help. Change your fuel filter could be clogged with something, check the fuel pump to make sure it is putting out enough fuel. How about your coil have that checked too. These are ideas pulled off my repair manuals, hope they help you and good luck!
