I have a 93 SC that stalled at a stop light, acted like it was flooded. Took awhile but I finally got it started, ran fine for a couple of days. Then it would not start. Let it sit overnight and the next day it started and ran fine. Had a mechanic look at it, replaced the engine module, still has the same problem. He does not have an engine tester for a SC. Any suggestions?
