I have a 1995 900S conv., 2.3l that is hesitating under wide open throttle, even at low (2200) RPM. It will accelerate for about 3 seconds, then buck sharply. The recent services performed by the dealer for the previous owner to try to cure the problem were: new temp. sensor, new fuel pump. The distributor is new as well as the wires and plugs. I have replaced the thermostat (stuck open) and a few vacuum hoses that were cracked. The rubber intake piece that attaches to the airflow meter and the intake is in good shape. Any ideas as to what I should look at next? The check engine light came on the last time it acted up, cutting off at idle. Thanks for any help.

This is likely to be a fuel issue, since it only happens at WOT. Things to check: fuel filter and pressure regulator.
Jody,
Are you using high octane (i.e. knock resistant) gas? Lower octane gasoline in a Saab Turbo can provoke knocking, which in turn activates a built in knock sensor. Try premium gas.

The NG 900 S 2.3L is naturally aspirated.
