ses light & running rough after rain? 98 bolt-on trans am a4--- Ive had no problems or ses lights on the dash since my dyno tune. Today the car was running fine then we got the 1st good rain in about 2 months here in texas on my way home- I stopped at the post office and left it running for a minute. When i came out i noticed it sounded rough and the service engine light was on. When i took off it was very rough and had no power- I was just gonna creap home real slow because it wasnt even gonna get up to speed- then all the sudden the power came back and it easily got up to speed. It feels like its running decent now, but the service code is still on. Is it normal for rain to affect it like that? Im thinking maybe it did something with my o2 sensor maybe. JUst wondering if anyone else has had similar problems???

Haven't had a ses light in awhile, knock on wood that I don't but one
of the things that set off ses was a vacuum leak where the egr stick
goes into the intake manifold. If you hear a lot of hissing there you might replace the o ring and reinstall the egr stick as perpendicular as you can get it.
