I just read the following codes on my 1995 850 turbo wagon with 132K miles:

2-3-2: Long Term Fuel Trim, idling
3-1-5: EVAP System

Can anyone clue me into what I should be looking for as a solution? Is there a common cause for these faults, or do I need a mechanic to investigate further. Anything specific I should check right off the bat. The 3-1-5 code comes back as soon as I clear it. The 2-3-2 is new and won’t clear either. Exhaust smells like rotten eggs too. Thanks for the help!

Unless you live in state that does emmissions testing, ignore the 315 code for a while. It is probably the valve at the charcoal cannister line that needs to be replaced.
No car should smell from sulphur, you are running way too rich. Clean the throttle body and the MAF. You may also have vacuum problems, so check the elbows for cracks - especially the one just behind the power steering pump and under the battery. Have you done a basic tune up lately?

Thanks Klause -

Last tune up was just under 30K ago. I'll work on the MAF and throttle body this week and see if that does it. I guess my biggest complaint is the sulphur smell in the exhaust.

Then it is time for a tune up.
