I searched and didnt find nothing. I had a jdm mr diverter valve installed for less than a day. Took it off because it shuddered when you let off the gas slightly, and during traffic it would almost stall the car. Installed the stock valve, now the stock one seems to shudder worse than the mr? The car feels like s*it up top also. Anyone have any ideas? Never noticed the stock one doing it before.

 

Sorry cant help you. But if your getting rid of your JDM mr diverter valve (BOV?) let me know because I want it. Where did you get it? thanks

 

have hade mine for the life of the car , no problem at all . all the 12,000 miles it has

 

stupid question but, did you put it back in the right way?

 

^ LOL I knew that question would come up, but yea its in the right way. By the way the mr valve is already sold.

 

Yea, sounds like it was deffinetly put in backwards....no worries, I did the same thing when I had my mr valve...doh!

 

i put mine in backwards also, i thought there was a bird under my hood with the fluttering noise it made.

 

When its in correct the little nipple for the hose on the valve should be facing slightly up torwards the passenger seat..correct?

 

Try running the stock airbox. I'm guessing the MAF meter is spiking due to the increased air. You probably need the ecu tuned for your intake.

 

I have the stock airbox with just a drop-in filter, weird i just took the car out and it seemed fine??

 

If you have a vacuum pump you might want to check the dv with that. Stock they are supposed to open at about 15 1/2" to 16 inches of vacuum. I checked mine and it was dead on to the factory numbers.

 

Hey if you could , could you give me some more info. on this, thanks.

 

always take pics of before so u cant screw up after. dont have a camera search how to section for information. that helps.
