97 SC2 Low idle hesitation on acceleration 5sp.

[lazyman73]

I just purchased this 97 SC2, 136,000 miles on it and it has a slight problem. Typical day driving: When car is cold not a problem with any acceleration or shifting hesitations. When the car warms up about 10-15 minutes later, shifting is no problem but there is a slight hesitation in all gears when the idle drops between 1800-2400 rpm. After it gets past the hesitation point the car runs strong until I shift. Another food for thought is that if I keep my foot down on the accelerator when shifting the car runs throught the gears without a single bit of hesitation. This car has me stumped and need some guru about saturns to help me finger this one out.
