I owned a 95 SC1 manual many years ago. It acted like that for me, and stalled on a regular basis. Turned out the EGR valve was bad. I replaced it and all those problems went away. I'm not sure how to test it, but two bolts and you can pull the valve and make sure it's not crudded up. Don't use solvents or you can damage the diaphragm in there, just use a toothbrush and some rags. You should also use a new gasket when you reinstall it, although as a test you can reuse the old one if it's not damaged. While you do that check for obvious intake and vacuum leaks. There may even be a vacuum line going to the EGR valve. Hope that helps.
