Recently my 95 4 cyl HB has been running pretty rough. Mostly accelerating through 2nd gear. It has even stalled a couple times at idle. I noticed one day a very rich, sulfur type smell out of the exhaust pipe. I also notice a very rich fuel smell out of it too on other days. It is very inconsistent. Some days the exhaust will seem fine. I'm baffled. At first I thought it was dirty injectors so I ran some techron in it to no avail. I checked the ECU for codes and came out with 55 (no malfunction) as my check engine light never came on. What could be the problem?? Thanks for any advice

Thanks. Yeah I'm sure I could use a tune-up. I thought about the cat being bad too. Is there a way you can check those? I'd hate to buy a new one and that not be the problem.
