Does it start up and idle fine?
Do you have any leaks?
Check fuel pressure, might be a fuel pump going south.
Check out all your vacuum lines. These cars are getting older and the rubber lines might develop cracks in them.

is the motor stock? Maybe re-check the gap on the plugs. Plug wires aren't resting on the headers?
