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.

 

yea actually i had tightened it since that was the only thing i changed and it seems to have been the problem. only thing was i tightened it before i drove 30 min to my house where i posted this and it was still doing it... guess the ecu had to get used to it?

 

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

Also, how is your MAF setup?

 

wut do you exactly mean by maf setup? the sensor's where mazsport's cai has it placed.

like this



not mine but looks almost exactly like it

 

Agree with chicken .Sounds like you got a wet maf from the hose down.

 

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.

 

/\ or just go for a drive . I'll clear itself before too long
