Car Rough Idle And Stalling. FI

Ok so I've been reading the threads about rough idles and stalling.

Have greddy kit w/ mm's base fi map, fix no#2, oil catch can. BHR ignition coils. New spark plugs installed a week ago.

Car's been running fine for the last 2-3 weeks. This started happening yesterday after I tuned my bov after hearing what sounded like a weak compression surge. only thing after that was I chilled at my house for about an hour then came outside, sprayed down my car with a hose to remove the spots from the rain, then started driving.

immediately had rough idle and rough rpm increase when revving. then car started stalling today when i release the clutch and let off the accelerator when coming to a stop or turn.

all feedback welcome.
and btw i'll be gone for 2 weeks starting from tomorrow for military training so i'll get to this when i get back.
i will be checking this thread til tonight though.

I would resort the problem back to the BOV. Maybe too loose. I would think it would resemble symptoms of a vacuum leak.

It's possible your MAF sensor got wet, I would check that

Also, how is your MAF setup?

I was just making sure you were using a good MAF housing, otherwise with the COBB your car will run like ***. The MAF is very sensitive.

But yeah, it sounds like your MAF got wet. I would pull it out, spray it with some good electrical contact cleaner, let it air dry fully (a few hours) then reinstall.
