Engine is smoother and much faster when humid or raining

Already asked on USMB, but wondering specifically what us legacy guys have to say. I was about to replace the o2 sensor, but would that even do anything in this case? Maybe I should look for a MAF instead. Stock one I took out and cleaned but may have touched the end of it damaging it when I put it down. When I removed it, it was the day I brought the car home and never really opened up the throttle much so no real comparison.

Things replaced, CTS, knock, plugs, wires, seafoamed a trillion hoses, air filter.

lol ok well bought some new plugs. Going to gap them at .38in then replace the o2.

or switch the turbo all together. it spins to 140,000 rpm, a little extra friction, could make it tempermental. anyway im just tryin to help cause i have swapped for new parts and massaged the vacuum system too. mines still doin it. waste of time and money!

I have yet to switch my turbo and fix an exhuast leak, but im allmost possitive my BOV is the biggest problem. good luck! if you fix it gimme a shout back.

if you know you have a exhaust leak its probably the issue. Maybe i have a exhaust leak too. I already tried a bov didnt really do anything.
